Variable Gain Amplifiers

PRODUCTS AND SERVICES

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.

The VGLCDLA30RPDC is a variable gain GPS line amplifier featuring a range of 0 to 30 dB with LCD display and push button controls in 1 dB increments. The frequency response covers L1/L2/L5 and Galileo/GLONASS bands. The push button control along with the LCD display allows users to make precise adjustments quickly and view the output power at any given time to make testing more efficient.

RFMD’s RFDA0015 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range. The 6-bit digital step attenuator is programmed with a parallel mode control interface.
Two models of digitally controlled variable gain amplifiers operating in the 400- to 2700-MHz range are available from RFMD. They both featured power-up programming, 12-bit SPI serial control programming, single +5V supply, a gain control range of 31.5dB, dual channel VGA, full internal matching and no external bias inductors. Two 6-bit digital step attenuators, and 50dBc channel isolation. These amplifiers can be used in cellular, 3G infrastructure, WiBro, WiMax, LTE, Microwave Radio, and High Linearity Power Control applications.
The MPS-032701A-82 variable gain amplifer is an internally matched GaAs FET amplifier in a surface mount ceramic package. This variable gain amplifier is ideal for digital communications applications where excellent gain linearity and high efficiency at a 5 Volt bias is required...

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

ALM-80210 is a 0.25W Analog Controlled Variable Gain Amplifier which operates from 1.6 GHz to 2.7 GHz.
