New version of Receiver Protection Unit

Chris Moulding

We have released a new version of the Receiver Protection Unit so that the maximum output is below the strict 10 dBm limit for SDRPlay receivers.

In the previous version the maximum output level was 17 dBm which is OK for the majority of receivers but was still too high for SDRPlay receivers.

The protection unit uses a range of methods such as a gas discharge tube, isolation transformer and cascaded diode limiters to bring excessive RF power down to a safe level.

If connected to a ground it will also drain static electricity from the antenna and a 10 kA gas discharge tube will help with nearby lightning strikes.

With the latest version you could connect a 150 W transmitter for that ham radio "Oops!" moment without exceeding the SDRPlay receiver limit.
