QSOP-16
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.

Input IP3
1. For IP3 measurements, RFIN = -24 dBm, this low RF IN level gets amplified through the LNA. 2. For IP3 measurements, RFIN2 = RFIN1 + 10 MHz, LO = RFIN1--140 MHz. 3. For IP3 measurements, IP3 = IMR/2 + PIN. 4. RF IN to IF Isolation is typically 0 dB. 5. Reverse Isolation is measured from IF to RFIN with the IF at -10 dBm, LO at +13 dBm. 6. The amplifier has a normal gain of 12.5 dB, 3V bias and 14.0 dB, 5V bias. Amplifier typical Noise Figure = 1.5 dB. 7. NFT = NF1 + (NF2 - 1)/G1

The spurious table shows the spurious signals resulting from the mixing of the RFIN and LO input signals, assuming down conversion. 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
