Description
The MSA-1000 is a high performance, medium power silicon
bipolar Monolithic Microwave
Integrated Circuit (MMIC) chip.
This MMIC is designed for use in a
push-pull configuration in a 25␣ Ω
system. The MSA-1000 can also be
used as single-ended amplifier in a
50␣ Ω system with slightly reduced
performance. Typical applications
include narrow and broadband RF
The MSA-series is fabricated using
HP’s 10 GHz fT, 25␣ GHz f MAX,
silicon bipolar MMIC process
which uses nitride self-alignment,
ion implantation, and gold metallization to achieve excellent
performance, uniformity and
reliability. The use of an external
bias resistor for temperature and
current stability also allows bias
flexibility.

Notes:
1. Permanent damage may occur if any of these limits are exceeded.
2. TMounting␣ Surface (TMS) = 25°C.
3. Derate at 100 mW/°C for TMounting␣ Surface > 130°C.
4. The small spot size of this technique results in a higher, though more
accurate determination of θjc than do alternate methods.

Notes:
1. S-parameters are de-embedded from 100 mil BeO package measured data using the package model found in the
DEVICE MODELS section.
2. S-parameter data assumes an external 80 pF capacitor. Low frequency performance can be extended using a larger
valued capacitor.
