| Voltage Variable Absorptive Attenuator 1700 - 2200 MHz V 2.00 MAAVCC0002 Features n n n n n n n n n n CSP-8, 28 Lead, 6mm Input IP3: +31 dBm Min (Full Attenuation Range) Input IP3 is 15 -20 dB Better than GaAs Linear Operation: +20 dBm Min. Plastic, 28 Lead, 6 mm CSP, SMT Package 35 dB Dynamic Range (With 30 mA Bias Current) Single Control Voltage 50 ohm Impedance Linear Driver, DR65-0002, Available Test Boards are Available Tape and Reel Packaging Available Description M/A-COM's MAAVCC0002 is a PIN diode based voltage variable attenuator. This device is in a 6mm square, 28 lead, plastic CSP package, suitable for surface mounting on PCBs. These attenuators have linear operating power and input intercept point levels 15 - 20 dB better than GaAs FET MMIC voltage variable attenuators. They are ideally suited for use where low distortion, high linear operating power and high dynamic range are required. These devices are optimized for the PCS and UMTS frequency bands, but exhibit excellent performance and repeatability over the entire specified frequency band. The MAAVCC0002 is ideally suited for wireless communications systems. Package outline conforms to JEDEC standard MO-220B.
