Description

Celeritek’s CFB0303 is a high performance GaAs

PHEMT with 600 µm gate width and 0.25 µm gate length.

The low noise figure and high intercept point of this device

makes it well suited for use as the low-noise amplifier of the

base station receiver in PCS, Japanese PHS, AMPS, GSM and

other communications systems. The CFB0303 is in an indus-

try-standard 70 mil package. It is surface mountable and

available in tape and reel.
