The ASF255, a IF gain block amplifier MMIC, has a

high linearity, high gain, and high efficiency over a

wide range of frequency, being suitable for use in

both receiver and transmitter of telecommunication

systems up to 3 GHz. It has an active bias network

for stable current over temperature and process

variation. The amplifier is available in an SOT-89

package and passes through the stringent DC, RF,

and reliability tests
