DESCRIPTION
The UPC8128TB is a Silicon RFICs designed as a buffer
amplifier for cellular or cordless telephones. This low current
amplifier operates on 3.0 V and is housed in a 6 pin super
minimold package.
The IC is manufactured using NEC's 20GHz f
T
NESAT™ III
silicon bipolar process. This process uses silicon nitride
passivation film and gold electrodes. These materials protect
the chip surface from external pollution and prevent corrosion/
migration. Thus, the IC has excellent performance, uniformity
and reliability.

Description
Signal input pin. An internal
matching circuit provides a 50
Ω
match over a wide bandwidth.
This pin must be coupled to signal
source with a blocking capacitor.

OUTPUT
Vcc through external
inductor.
Signal output pin. This output is
designed as an open collector.
Due to the high impedance output
this pin should be externally
equipped with an LC matching
circuit.

Power supply pin. This pin should
be externally equipped with a bypass
capacitor to minimize ground
impedance.
Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground
pattern on the board should be
formed as wide as possible. All the
ground pins must be connected
together with wide ground pattern
to minimize impedance difference.
