SA65-0003

Down Converter, 1500 - 2000 MHz V 1.00 SA65-0003 Features n n n n n n n QSOP-16 LNA Mixer integration. Typical conversion gain of 7 dB. Typical Two-Tone IM Ratio of ≥ 50 dBm. LO Drive-Level: +13 dBm. Surface Mount QSOP16 Package. Low Cost/High Performance. 50 ohm Nominal Impedance. Description M/A-COM’s SA65-0003 is an integrated assembly containing a GaAs FET MMIC LNA and GaAs FET mixer. This device is packaged in a 16-leaded QSOP plastic surface mount package. The amplifier can be biased with either +3V or +5V, the mixer requires no DC bias. The conversion gain of the integrated combination is typically 6 dB at +3V bias and 8 dB at +5V bias. The SA65-0003 is ideally suited for RF/IF communications applications requiring down conversion with some gain. This MCM contains a mixer that is fabricated using a mature 1-micron GaAs process, it also contains an LNA that is fabricated using a low cost mature 0.5-micron gate length GaAs MESFET process. Both die feature full passivation for increased performance and reliability.
