SGA-7489

RoHS Compliant

& Green Package

Product Description

The SGA-7489 is a high performance SiGe HBT

MMIC Amplifier. A Darlington configuration featuring

SGA-7489Z

DC-3000 MHz Silicon Germanium

HBT Cascadeable Gain Block

1 micron emitters provides high F and excellent

thermal perfomance. The heterojunction increases

breakdown voltage and minimizes leakage current

between junctions. Cancellation of emitter junction

non-linearities results in higher suppression of

intermodulation products. Only 2 DC-blocking ca-

pacitors, a bias resistor and an optional RF choke

are required for operation.

Product Features

The matte tin finish on Sirenza’s lead-free package

utilizes a post annealing process to mitigate tin whis-

ker formation and is RoHS compliant per EU Direc-

tive 2002/95. This package is also manufactured

with green molding compounds that contain no an-

timony trioxide nor halogenated fire retardants.

• Now available in Lead Free, RoHS

Compliant, & Green Packaging

Test Conditions:

NOTE: The recommended operating current in the preliminary datasheet was 130mA. Supplemental measurements have since shown

that an operating current of 115mA results in optimal RF performance over temperature. Continued operation at 130mA is reliable,

however, the recommended operating current has been changed to 115mA.
