8473B/003/101 has Positive Polarity output, No matched response
Keysight 8473B Low-Barrier Schottky Diode (LBSD) detector has been widely used for many years in a variety of applications including leveling and power sensing. It offers good performance and ruggedness.
Keysight 83051A 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 45 MHz to 50 GHz allows the designer to replace several narrow bandwidth amplifiers with a single Keysight amplifier, eliminating the need for crossover networks or multiple bias supplies.
