Variable Gain Amplifier -3 to 23dB Variable Gain Amplifier -3 to 23dB

The VGLA20RPDC GPS Variable Gain Line Amplifier is a one input, one output device featuring a variable gain block with 26dB of dynamic range.

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.
Digital Controlled Variable Gain Amplifier 2000MHz To 2800MHz: RFDA2046 Digital Controlled Variable Gain Amplifier 2000MHz To 2800MHz: RFDA2046
RFMD’s RFDA2046 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range with noise figure less than 5.2dB in its maximum gain state. The gain of the 6-bit digital step attenuator is programmed with a serial mode control interface (SPI). The RFDA2046 is packaged in a small 6.0mm x 6.0mm leadless laminate MCM, which contains plated through thermal vias for ultra-low thermal resistance. This module is easy to use with no external matching components required.
