Description
Package/ SOT-343 (SC-70)
Hewlett Packard’s HBFP-0420 is a
Outline 4T
high performance isolated
collector silicon bipolar junction
transistor housed in a 4-lead SC-70
(SOT-343) surface mount plastic
package.
HBFP-0420 provides an associated
gain of 17 dB, noise figure of
1.1 dB, and P
1dB
of 12 dBm at
1.8 GHz. Because of high gain and
low current characteristics,
HBFP-0420 is ideal for
cellular/
PCS handsets
as well as for
C-Band and Ku-Band
applications.
This product is based on a 25 GHz
transition frequency fabrication
process, which enables the
products to be used for high
performance, low noise applica-
tions at 900 MHz, 1.9 GHz,
2.4 GHz, and beyond.
Pin Configuration
Applications
• LNA, Oscillator, Driver
Amplifier, Buffer Amplifier,
and Down Converter for
Cellular and PCS Handsets
and Cordless Telephones
• Oscillator for
TV Delivery
and TVRO Systems up to
10 GHz

S and noise parameters are measured
on a microstrip line made on
0.025 inch thick alumina carrier. The
input reference plane is at the end of
the base lead, the output reference
plane is at the end of the collector
lead. S and noise parameters include
the effect of four plated through via
holes connecting emitter landing pads
on the top of test carrier to the
microstrip ground plane on the
bottom side of the carrier. Two
0.020 inch diameter via holes are
placed within 0.010 inch from each
emitter lead contact point, one via on
each side of that point.
