Product Description
The RF2314 is a general purpose, low-cost, high performance amplifier
designed for operation from a 2.7V to 6V supply with low current consumption. The circuit configuration with resistive feedback allows for
broadband cascadable amplification. Feedback with capacitive compensation extends the bandwidth of the amplifier, and is designed for optimized noise figure. The device is unconditionally stable and internally
matched to 50. No external components are required. The RF2314 is
available in a very small industry-standard SOT 5-lead surface mount
package, enabling compact designs which conserve board space.

PCB Design Requirements
PCB Surface Finish
The PCB surface finish used for RFMD’s qualification process is Electroless Nickel, immersion Gold. Typical thickness is 3inch
to 8inch Gold over 180inch 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 processes. 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 3mil expansion to accommodate solder mask registration clearance around all pads. The centergrounding 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.
