VG111

www.DataSheet4U.com VG111 Product Features The Communications Edge TM Product Information PCS/UMTS-band Variable Gain Amplifier Product Description The VG111 is a PCS / UMTS-band high dynamic range variable gain amplifier (VGA) packaged in a low profile Pb-free / RoHS-compliant surface-mount leadless package that measures 6 x 6 mm square. The +22 dBm output compression point and +39.5 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 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.
