WJ Communication VG112
The VG112 is a PCS / UMTS-band high dynamic range variable gain amplifier (VGA) housed in a low profile Pb-free / green / RoHS-compliant surface-mount leadless QFN package that measures 6 x 6 mm square. The +30 dBm output compression point and +46 dBm output intercept point of the amplifier are maintained over the entire attenuation range, making the VG112 ideal for use in transmitter and receiver AGC circuits. The high gain of the dual-stage amplifier allows for more integration in a transceiver board while requiring minimal printed circuit board space.| Part No. | VG112 |
