Product Description
The VG111 is a PCS / UMTS-band high dynamic
range variable gain amplifier (VGA) packaged in a
6x6 mm surface-mount package. The +21 dBm
output compression point and +40 dBm output
intercept point of the amplifier are maintained over
the entire attenuation range, making the VG111 ideal
for use in transmitter and receiver AGC circuits and
as a variable gain stage following an LNA in high
dynamic range receiver front ends.
Superior thermal design allows the product to have a
minimum MTTF rating of 100 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.

Test conditions unless otherwise noted.
1. T = 25oC, Vdd = +5 V, Frequency = 800 MHz in an application circuit.
2. 3OIP measured with two tones at an output power of +10 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. The gain variation range is measured with 16 mA of current on gain control pin 5.
4. The junction temperature ensures a minimum MTBF rating of 1 million hours of usage.
