Digital operation modes are becoming more and more popular in amateur radio. Here transmission protocols are in use which require extremely short latency times for receive and transmit switching. With TDMA schemes like MOTOBRO or DMR they are below 1 Millisecond. Standard power amplifiers with relays are unusable.
The P40X amplifier uses pin-diode switches and doesn’t have that limitations. It is perfectly suited for modulation schemes with constant envelope like FM, DMR, DStar, GMSK and C4FM.
Frequency range: 420…450MHz
Output power: up to 40 W (depending on supply voltage and drive power)
Supply voltage: 11 … 13,8 V
Input power: 0.4 … 5 W
RX/TX delay <100 micro seconds
