Product Description
Low Noise Transmit Driver
Amplifier
The RF2361 is a low noise amplifier with a very high dynamic range designed for
digital cellular applications. The device functions as an outstanding front end low
noise amplifier or power amplifier driver amplifier in the transmit chain of digital
subscriber units where low transmit noise power is a concern. When used as an
LNA, the bias current can be set externally. When used as a PA driver, the IC can
operate directly from a single cell Li-ion battery and includes a power down feature
that can be used to completely turn off the device. The IC is featured in a standard
SOT 5-lead plastic package.

NOTE: The RF2361 is a non-Pb-free product. If a Pb-free product with the same
functionality and package is desired, please see the RF2878.

PCB Design Requirements
PCB Surface Finish
The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3μinch
to 8μinch gold over 180μinch nickel.
PCB Land Pattern Recommendation
PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and tested
for optimized assembly at RFMD; however, it may require some modifications to address company specific assembly pro-
cesses. The PCB land pattern has been developed to accommodate lead and package tolerances.

PCB Solder Mask Pattern
Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB
metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all pads. The
center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be
provided in the master data or requested from the PCB fabrication supplier.
