Description

The PS404 is a high performance InGaP HBT MMIC Amplifier and

consists of Darlington pair amplifiers that is internally matched to

75Ω input/output. The PS404 features high gain, high linear

performance, wideband operation, high reliability and low noise as a

CATV amplifier. The PS404 operates from a single voltage supply

and requires only two DC-blocking capacitors, a bias resistor and an

inductor for operation. The device is a general purpose CATV

amplifier that offers high dynamic range in a low cost surface-

mounted plastic SOT-89 package. All devices are 100% RF and DC

tested.
