Description
Hewlett-Packard’s HPMX-3002 is
a silicon microwave monolithic
integrated circuit driver amplifier
housed in a S0-8 surface mount
plastic package. It operates over
the 150 - 960 MHz frequency
range, and at 900 MHz it produces
+23 dBm of saturated output
power, has 30 dB of small signal
gain and a 50 dB power control
range. The amplifier has a wellmatched input, and an open
collector output which provides
good linearity and efficiency and
is easy to externally match to 50
Ω for optimal power output.
This device is well suited as a
driver amplifier for European
GSM (Global System for Mobile
communications) portable and
mobile telephone systems, or as
the output stage for other low
cost applications such as 900 MHz
ISM band spread-spectrum.
The HPMX-3002 is fabricated with
Hewlett-Packard’s 15 GHz f
t
ISOSAT-II process, which
combines stepper lithography, ion
implantation, self-alignment
techniques, and gold metallization
to produce RFICs with superior
performance, uniformity and
reliability .

HPMX-3002 Pin
Description
Ground (pins 1,3,7,8):
This RFIC is ground sensitive. A
short path to ground with minimal
parasitics must be provided on all
ground leads to prevent stability
problems. The PC board should
be 0.032" or less in thickness.
Multiple vias should be placed
near the ground leads. Failure to
properly ground this device can
lead to positive return gain and
possible stability problems. We
suggest performing a stability
analysis using the device s
parameters and a description of
the inductance of your ground
path. A recommended board
layout is shown on the final page
of this data sheet. Pins 7 and 8
also provide the primary thermal
path for heatsinking the device.
V
CC1
(pin 2):
This pin provides the DC bias for
the amplifier driver stages, and
has an operating range of 4.5 to 6
V (5 V nominal). It should be
bypassed close to RFIC body
using a 1000 pF capacitor.
RF
in
(pin 4):
The impedance of this RFIC is
well matched to 50 Ω from 100
MHz to 1100 MHz. Normally, no
additional impedance matching is
required. S-parameters are
provided should the designer need
to “fine tune” the input match. Pin
4 must be AC coupled to
generator (1000 pF typ. blocking
capacitor). The nominal drive
level is -6 dBm, and under normal
operating conditions should not
exceed 0 dBm.
Control (pin 5):
Applying a DC voltage to this pin
adjusts the gain of the last 2
stages of the RFIC over a 50 dB
range. Pin 5 has an operational
range of 0 to 2.5 V. The power
control function is designed for
operation in the 800 - 1000 MHz
frequency range, and decreases in
adjustment capability at lower
frequencies – refer to the
performance graphs (figure 3).
RF
out
and V
CC2
(Pin 6):
Pin 6 connects to the open collector of the output stage. A power
match is required at this pin. The
typical match for operation
between 800 and 1000 MHz
consists of a shunt L (8 nH typ.)
and a series C (27 pF typ.), with
the series C also serving as the
blocking capacitor. The s
parameter data should be used to
generate matches for other
frequency bands.
