VG111 The Communications Edge TM PCS/UMTS-band Variable Gain Amplifier Applications GND 5 GND 6 GND Vctrl 7 GND GND The VG111 is a PCS / UMTS-band high dynamic range variable gain amplifier (VGA) packaged in a 6x6 mm surface-mount package. The +22 dBm output compression point and +39 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. 4 3 2 1 GND 8 28 GND GND 9 27 GND Amp GND 10 25 RF OUT GND 12 24 GND Variable Attenuator GND 13 23 GND GND 14 17 18 19 20 N/C GND Function Gain Control No Connect RF Input RF Output / DC bias Ground 21 N/C 16 GND 22 GND 15 GND Superior thermal design allows the product to have a minimum MTTF rating of 1000 years at a mounting temperature of +85 C.
