RF frequency coverage is from 0.8 to 6 GHz and IF coverage is from 50 to 700 MHz. Packaged in the SOT-363 package, this 4.0 sq. mm. package requires half the board space of a SOT-143 and only 15% the board space of an SO-8 package. At 1.9 GHz, the IAM-91563 pro- vides 9 dB of conversion gain, thus eliminating an RF or IF gain stage normally needed with a lossy mixer. LO drive power is nominally only -5 dBm, eliminat- ing an LO buffer amplifier. The 8.5 dB noise figure is low enough to allow the system to use a low cost LNA. The -6 dBm Input IP3 provides adequate system linearity for most commercial applications, but is adjustable to 0 dBm. The circuit uses GaAs PHEMT technology with proven reliability, and uniformity. The MMIC consists of a cascode FET struc- ture that provides unbalanced gm modulation type mixing. An on- chip LO buffer amp drives the mixer while bias circuitry allows a single +3V supply (through a choked IF port). The LO port is internally matched to 50 Ω. The RF and IF ports are high imped- ance and require external match- ing networks.
