SIRENZA NGA-386

Preliminary
NGA-386
Product Description
Sirenza Microdevices’ NGA-386 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMIC Amplifier.
Designed with InGaP process technology for improved reliability,
a Darlington configuration is utilized for broadband performance
up to 5 Ghz. The heterojunction increases breakdown voltage
and minimizes leakage current between junctions. Cancellation
of emitter junction non-linearities results in higher suppression of intermodulation products.

Mounting Instructions
1. Use a large ground pad area under device pins 2
and 4 with many plated through-holes as shown.
2. We recommend 1 or 2 ounce copper. Measurements
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.
Part Identification Marking
The part will be marked with an “N3” designator on
the top surface of the package.
