A74 / SMA74

Cascadable Amplifier

5 to 500 MHz

Rev. V4

Features

Product Image



HIGH GAIN - TWO STAGES: 30.0 dB (TYP.)

MEDIUM OUTPUT LEVEL: +8.5 dBm (TYP.)

WIDE POWER SUPPLY RANGE: +8 TO +15 VOLTS

LOW VSWR: <1.3:1 (TYP.)

Description

The A74 RF amplifier is a discrete hybrid design, which uses

thin film manufacturing processes for consistent performance

and high reliability.

This 2 stage bipolar transistor feedback amplifier design

displays impressive performance over a broadband

frequency range. An active DC biasing network insures

temperature-stable performance.

Both TO-8 and Surface Mount packages are hermetically

sealed, and MIL-STD-883 environmental screening is available
