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.

The number of dB below the conversion loss level indicates the mixing products. The lower frequency mixing term is shown for two different input levels. The top number is for an RFIN power level of –19 dB; the lower number is for –29 dB. Assuming the LNA gain is approximately 14 dB, the mixer input will see approximately –5 dB and –15 dB. |mFRF - nFLO|, RF = -19 dB RF = 1850 MHz |mFRF - nFLO|, RF = -29 dB LO = 1710 MHz 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
