Description
Hewlett-Packard’s HPMX-3003
combines a Low Noise Amplifier,
GaAs MMIC switch, and 27.5 dBm
power amp in a single miniature
28 lead surface mount plastic
package. This RFIC would
typically serve as the “front end”
and power stage of a battery
operated wireless transceiver for
PCS or ISM band use. Each
section of the RFIC can also be
used independently.
The single-supply LNA makes use
of the low noise characteristics of
GaAs to create a matched, broad-
band amplifier with target perfor-
mance of 13 dB gain and 2.2 dB
noise figure. The switch provides
+55 dBm IP3 for linear operation.
The power amplifier produces up
to 820 mW with 35% power added
efficiency.
The HPMX-3003 is fabricated with
Hewlett-Packard’s GaAs MMIC
process, and features a nominal
0.5 micron recessed Schottky-
barrier-gate, gold metallization,
and silicon nitride passivation to
produce MMICs with superior
performance, uniformity and
reliability.
