Functional Diagram
General Description
Gain: 22 dB
The HMC478MP86 is a SiGe Heterojunction Bipolar
Transistor (HBT) Gain Block MMIC SMT amplifier
covering DC to 4 GHz. This Micro-P packaged
amplifier can be used as a cascadable 50 Ohm
RF/IF gain stage as well as a LO or PA driver with
up to +20 dBm output power. The HMC478MP86
offers 22 dB of gain with a +32 dBm output IP3
at 850 MHz while requiring only 62 mA from a
single positive supply. The Darlington feedback
pair used results in reduced sensitivity to normal
process variations and excellent gain stability over
temperature while requiring a minimal number of
external bias components.

107087 Evaluation PCB
The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads should be connected directly to the
ground plane similar to that shown. A sufficient
number of VIA holes should be used to connect the
top and bottom ground planes. The evaluation board
should be mounted to an appropriate heat sink. The
evaluation circuit board shown is available from
Hittite upon request.
** Circuit Board Material: Rogers 4350
