ASB ASF255

ASF255
5-3000 MHz MMIC Amplifier
Features
Description
·22.4 dB Gain at 150 MHz
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

Mounting Recommendation (in mm)
Note: 1. The number and size of ground via holes in
a circuit board is critical for thermal and RF
grounding considerations.
2. We recommend that the ground via holes
be placed on the bottom of the lead pin 2
and exposed pad of the device for better RF
and thermal performance, as shown in the
drawing at the left side.
