Variable Gain Amplifiers


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.

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

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

  • 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)

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.
