Intended for use with the VTX 5000 series transmitters, the VTA 5000 series power amplifiers are built around an efficient input RF limiter followed by a high efficiency class C amplifier chain, the spurious purity of which is given by an output RF filter.

The VTX 5000 series transmitter delivers 20 W (or 10 W) constant output power whatever the output level between 17 dBm (50 mW) and 36 dBm (4 W).

Intended for linear amplification or COFDM application the VTA 5040 L power amplifiers is built around an high efficiency class A amplifier chain, the spurious purity of which is given by an output RF filter.
