Variable Gain Amplifiers

ETL Systems offers a series of fixed-gain tubular amplifiers with 10, 15, 20, 25 or 30 dB gain that operate in the L-band (850-2150 MHz). These amplifiers are available in DC pass biased from either RF port, DC block biased from output port, 10 MHz and DC pass biased from either RF port, DC blocked biased from input port, 10 MHz and DC block biased from output port, or 10 MHz and DC block from input port. Typical field applications for these devices include telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks.

FEATURES

• Gain can be adjusted continuously (0–15 dB) by applying a DC control voltage to the control pin with an external resistor in series (x 470 ohms)

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 VMMK-3503 .5-18 GHz Variable Gain Amplifier in WaferCap SMT Package is ideal for 2.4, 3.5, and 5-6 GHz WLAN and WiMax, 802.16 & 802.20 BWA systems, Radar and ECM systems, UWB, and generic IF amplifier and VGA applications.

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

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

ETL Systems offers a series of Variable Gain Amplifiers operating in the L-band (850-2150 MHz). These amplifiers have 0 to 30 dB gain settable in 1 dB gain steps with a built in regulator. Model options are available with end-to-end connectors or connectors on the same face, and are either in-line powered or externally powered. Field applications for these devices include telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks.

The device provides an exceptionally high OIP3 level which is maintained over a wide attenuation range.
