3 Tips for RF PCB Layout

Because the radio frequency (RF) circuit is a distributed parameter circuit, skin effect and coupling effect are prone to occur in the actual work of the circuit, so in the actual PCB design, it will be found that the interference radiation in the circuit is difficult to control, Such as: mutual interference between digital circuit and analog circuit, noise interference of power supply, interference caused by unreasonable ground wire, etc. Because of this, how to weigh the pros and cons in the PCB design process to find a suitable compromise, to reduce these interferences as much as possible, and even to avoid the interference of some circuits, is the key to the success or failure of the RF PCB design. From the perspective of PCB LAYOUT, this article provides some processing skills, which are of great use to improving the anti-interference ability of radio frequency circuits.To get more news about Cavity PCB, you can visit pcbmake official website.

1.RF layout

What we discussed here is the layout of the components of the multilayer board. The key to the layout of components is to fix the components on the RF path. By adjusting its direction, the length of the RF path is minimized, and the input is far away from the output, and the high-power circuit and the low-power circuit are separated as far as possible. The signal is far away from high-speed digital signals and RF signals.

1.1 One-line layout

The components of the RF main signal are arranged in a straight line as much as possible, as shown in Figure 1. However, due to the limitation of PCB board and cavity space, it cannot be laid out in a straight shape in many cases. At this time, L-shaped layout can be used. It’d be better not to use U-shaped layout (as shown in Figure 2). When it is unavoidable, it’d be better to increase the distance between input and output to at least 1.5cm. In addition, when using an L-shaped or U-shaped layout, the turning point should not turn as soon as it enters the interface, as shown on the left in Figure 3, but after a slight straight line, as shown on the right in Figure The feed inductance of the bias circuit is placed perpendicular to the RF channel, as shown in Figure 6, mainly to avoid mutual inductance between inductive devices. In order to use the space reasonably, the devices can be arranged in a 45-degree direction to make the RF line as short as possible, as shown in Figure 7. 2.RF Routing

The overall requirements for wiring are: RF signal traces are short and straight, reduce line abrupt changes, drill fewer holes, and do not intersect with other signal lines, and add as many ground vias as possible around the RF signal line.

World of Warcraft fans are counting down to the launch of WoW Classic on PC.And the good news is that there's not long to wait, because World of Warcraft Classic servers go live later today (August 26).To get more news about buy wow weapons, you can visit lootwowgold official website.

In case you're out of the loop, World of Warcraft Classic is a separate server option that rolls the game back to something closely resembling its original launch state.WoW Classic servers will go live at 11pm BST on August 26 for any fans playing in the UK. US fans are also in for a treat, as the servers go live on August 26 at 3pm PDT. Elsewhere, Blizzard has confirmed that European fans can play from midnight tonight (August 27), while players in Taiwan, Korea and Australia can join in at 6am, 7am and 8am local time on August 27.

It is, however, worth pointing out that Blizzard is anticipating lengthy queue times for the WoW Classic servers.“At this time, all realms that have a Full or High population tag are expected to experience extended queues," Blizzard explains. “We urge players on realms marked Full or High to plan to play on one of these new realms to avoid the longest queues, and to help spread the player population as evenly as possible and provide the best play experience for everyone.

”To help combat the potential server issues, Blizzard has created a series of new servers.Character creation limits have also been lifted, meaning players can now create ten characters per Classic realm. “We will remove the limitation on only creating a total of three WoW Classic characters per WoW account," Blizzard continues. "Thereafter, players will be able to create up to 10 characters per Classic realm, for a total of 50 characters across all Classic realms per WoW account." New World of Warcraft Classic servers include Incendius, Bigglesworth, Old Blanchy, and Westfall.WoW Classic will be available to anybody who subscribes to the core game.

If you want to play World of Warcraft Classic at launch, Blizzard has released a guide below... 1. Open the Battle.net desktop app and select World of Warcraft from the side menu. 2. Under the Version menu, select World of Warcraft Classic. If you have more than one World of Warcraft account, you’ll see a second dropdown for Account. Select the active account you wish to play on from that column. 3. Click the Install button. The progress bar will show you when the game is available to play. 4. Once the installation is complete, click the Play button.

World of Warcraft Classic players are currently delving through what will be the last content of the vanilla game experience. This past month, Blizzard introduced the Naxxramus raid to World of Warcraft Classic, as well as other lingering updates. Now, players are beginning to look forward to what comes next. The Burning Crusade, World of Warcraft's first expansion, has to be the inevitable next step. And if a recent rumored leak is any indication, Blizzard is already moving in that direction.To get more news about buy wow gold classic, you can visit lootwowgold official website.

In one of their recent videos, Youtuber and World of Warcraft content creator Staysafe TV provides details on a leak they claim to have seen. They say they first discovered the information in a World of Warcraft Classic forum, but that they ran the info by a "very trusted source" and that confirmed the details. To sum up the leak, Staysafe TV says that World of Warcraft Classic's Burning Crusade update is in the works and may arrive as soon as May 3.

In more detail, Staysafe TV explains that Blizzard is already planning the beta for the Burning Crusade update. This beta will tentatively arrive sometime in mid-February. A pre-patch will then follow on April 13, followed by the expansion's full launch. This fits the familiar pattern for World of Warcraft expansion launches, but doesn't have any firm evidence to support it outside of Staysafe TV's claimed anonymous source having confirmed it. As such, it's worth remaining skeptical.

The one aspect of this scenario that does sound realistic is how much it coincides with Blizzard's existing plans for BlizzCon. Blizzard delayed and is holding BlizzCon online this year. It will officially begin on February 19. Based on Staysafe's leak, that means that the Burning Crusade beta could start immediately after or around BlizzCon. As such, it would make for a fitting announcement during the show. It's all but certain that Burning Crusade is coming to World of Warcraft Classic in a matter of time. The alternative is Blizzard could reset the current servers and have players go through the base game all over again.

Shifting straight into Burning Crusade is likely to be much more successful, however. As with all unverified leaks and rumors, it's best to treat this as speculation above all. Staysafe TV isn't necessarily a reliable source and their leak isn't so robust as to be persuasive. Regardless, it's not unrealistic. With BlizzCon less than two months away, World of Warcraft Classic players won't have to wait long to find out the truth.
