Frequency:458MHz (std.); Any 10MHz wide segment in 420 - 470MHz

500mW RF power amplifier module

AFS2 amplifier module is intended to increase the transmitted power of a TR2M transceiver module. It provides transmit and receive paths, and can be simply 'dropped into' the aerial connection. The AFS2 may be usable with other 100mW output devices, such as LMT2 and TX2M
