Integrated Analog Controlled Variable Gain Amplifier: RFVA0016 Integrated Analog Controlled Variable Gain Amplifier: RFVA0016

This variable gain amplifier is ideal for broadband applications like cellular, 3G infrastructure, high linearity power control, WiBro, WiMax, LTE, and microwave radio. It has excellent linearity over a greater than 30dB gain control range and operates in the 400 MHz to 27000 MHz frequency range.

Variable Gain High Linearity, Low Noise Amplifier: RFLA1018 Variable Gain High Linearity, Low Noise Amplifier: RFLA1018
RFMD's RFLA1018 is an analog-controlled voltage-variable gain amplifier featuring high linearity and very low noise figure. This LNA with bypass mode and variable attenuator provides over 35dB of dynamic gain range. The RFLA1018 has a 3.3V control range with maximum gain at 0V. The LNA is temperature compensated to reduce gain variation. A noise figure of 0.65dB and an IIP3 of 2dBm make this component ideal for receiver input lineups. The RFLA1018 is packaged in a small 8.0mm x 8.0mm leadless laminate MCM. This module is internally matched to 50Ω on all RF ports, making it easy to use with no external matching components required.
