MAVR-000120-14110P

Overview

The MAVR-000120-14110P is a gallium arsenide flip-chip hyperabrupt varactor diode from MACOM Technology Solutions. It features constant gamma for linear tuning and is usable past 70 GHz. The device is fabricated on OMCVD epitaxial wafers with silicon nitride passivation and polyimide scratch protection. Electrical specifications include a breakdown voltage of 20 V minimum at 10 µA reverse current, and a maximum reverse leakage current of 100 nA at 14 V. Total capacitance ranges from 0.30 pF to 1.1 pF at 0 V reverse bias (1 MHz). At 4 V reverse bias and 50 MHz, the Q factor is typically 3000. Gamma is maintained between 0.9 and 1.1 within a 2 V to 12 V range.
