VARIABLE GAIN AMPLIFIER, VG-100

FEATURES

 3 dB BW, 1-100 MHz

 Variable gain

 Low distortion: -40 dBc @ +13 dBm

 Low phase noise: -161 dBc/Hz @ 10 Hz

-171 dBc/Hz @ 10 kHz

DESCRIPTION

The VG-100 is a variable gain amplifier with a minimum gain of +6 dB. Four gain switches on the front panel

provide additional gain in steps of +1 dB, +2 dB, +4 dB and +8 dB. The VG-100 features low phase noise and

a 100 MHz bandwidth. The input and output of the amplifier are AC coupled. Signal input and output

connectors are SMA. The VG-100 comes in a 2U half-rack enclosure and operates on 110/220 VAC.
