1001000 MHz Ultra Wideband Variable Gain Amplifier

The Skyworks SKY65142 is an ultra-wideband Variable Gain Amplifier (VGA) in a small footprint, 12-pin, 8 x 8 mm2, surface mount, multichip module (MCM). The module contains a variable voltage attenuator with gain control range of over 20 dB. The device is internally matched for 50 W on all RF ports.

The VGA maintains very linear performance of SKY65142 over a wide frequency bandwidth of 100 MHz to 1 GHz with a P1 dB greater than 27 dBm, OIP3 greater than 35 dBm and gain at zero attenuation greater than 20 dB.

All active circuitry of SKY65142  in the module is contained in a single Microwave Monolithic Integrated Circuit (MMIC). The device is fabricated using Skyworks high reliability Aluminum (Al) Gallium Arsenide (GaAs) Heterojunction Bipolar Transistor (HBT) process, which allows for single supply operation while maintaining high efficiency and good linearity.

The module SKY65142 can operate over the temperature range of -40 °C to +85 °C. A populated evaluation board is available upon request.
