Product Description
The VG025 is a high dynamic range variable gain
amplifier (VGA) capable of achieving an analog
attenuation range of up to 21 dB. The +21 dBm output
compression point and +40 dBm output intercept point
of the amplifier are maintained over the entire
attenuation range, making the VG025 ideal for use in
temperature compensation circuits or AGC loops.
The VG025 is available in a lead-free/green/RoHS-
compliant 16-pin 4x4mm QFN surface-mount package
with an exposed backside paddle to allow an MTTF
rating of over 1000 years at a mounting temperature of
+85o C. All devices are 100% RF & DC tested and
packaged on tape and reel for automated surface-mount
assembly.

1. Test conditions unless otherwise noted: 25oC, Vsupply = +5 V, in tuned application circuit. Vctrl
is the control voltage through the 120
dropping resistor as shown in the application circuit on page 2.
2. Specifications refer to the device at the maximum gain setting (Vctrl=0V). The input and output
return loss will be dramatically improved with an attenuation setting greater than 1 dB.
3. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
4. The gain variation range is measured as the difference in gain with Vctrl = 0 and 4.5V at 800 MHz.
5. This voltage refers to the V
CTRL
as shown in the circuit schematic on page 2. There should be a
series resistance of 120
