Description
Celeritek’s CFB0301 is a high performance GaAs
MESFET 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 CFB0301 is in an industry-standard 70 mil package. It is surface mountable and
available in tape and reel.
