Product Description
The RF3395 is a general purpose, low-cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50Ω gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 6000MHz.
The device is self-contained with 50Ω input and output
impedances and requires only two external DC-biasing
elements to operate as specified. The device is designed
for cost effective high reliability in a plastic package. The
3mmx3mm footprint is compatible with standard ceramic
and plastic Micro-X packages.

Note 1: All specification and characterization data has been gathered on standard FR-4 evaluation boards. These evaluation boards are
not optimized for frequencies above 2.5GHz. Performance above 2.5GHz may improve if a high performance PCB is used.
Note 2: The RF3395 must be operated at or below 80mA in order to achieve the thermal performance listed above. While the RF3395
may be operated at higher bias currents, 65mA is the recommended bias to ensure the highest possible reliability and electrical
performance.
Note 3: Because of process variations from part to part, the current resulting from a fixed bias voltage will vary. As a result, caution
should be used in designing fixed voltage bias circuits to ensure the worst case bias current does not exceed 80mA over all
intended operating conditions.

Description
No internal connections. It is not necessary to ground this pin.
Interface Schematic
RF input pin. This pin is NOT internally DC blocked. A DC blocking
capacitor, suitable for the frequency of operation, should be used in
most applications. DC coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instabil-
ity.
No internal connections. It is not necessary to ground this pin.
Ground connection.

No internal connections. It is not necessary to ground this pin.
RF output and bias pin. Biasing is accomplished with an external series
resistor and choke inductor to VCC. The resistor is selected to set the
DC current into this pin to a desired level. The resistor value is deter-
mined by the following equation:
R = (---V----S---U---P---P----L---Y----–----V----D----E---V---I--C----E---)
ICC

RF OUT
Care should also be taken in the resistor selection to ensure that the
current into the part never exceeds 80mA over the planned oper-
ating temperature. This means that a resistor between the supply and
this pin is always required, even if a supply near 5.0V is available, to
provide DC feedback to prevent thermal runaway. Because DC is
present on this pin, a DC blocking capacitor, suitable for the frequency
of operation, should be used in most applications. The supply side of
the bias network should also be well bypassed.
No internal connections. It is not necessary to ground this pin.

Ground connection. To ensure best performance, avoid placing ground
vias directly beneath the part.
