Amplifier 0.01 - 26.5GHz, 18dBm The 83006A microwave system amplifier is a compact, off-the-shelf amplifier designed for systems designers and integrators. This amplifier provides power where you need it to recover system losses and to boost available power in RF and microwave ATE systems. The ultrabroad bandwidth from 10 MHz to 26.5 GHz allows the designer to replace several narrow bandwidth amplifiers with a single HP (now Keysight) amplifier, eliminating the need for crossover networks or multiple bias supplies.
