What is it?

You have an NPR or NPR-H for ham radio high speed data transfer and you need additional TX power with litte bypass loss? Then this PA is the right choice.

Connectors: SMA Power: ~38 dBm Bypass loss: ~1 dB Frequency band: 70 cm

What makes it special?

It has high power RF switches, a VOX trigger and digital input switch. For the lowest packet error rate you should use the digital 3-5V line connected from the NPR and auto switch the PA.

Do I need to add something?

Yes, due to easier shipping I have added a aluminium metal plate of 3mm thickness. This is for GND and cooling purposes. But you need add little more cooling. So either add an additional alu block or a small fan. There is a 12V output connector for a FAN on the PA.
