| RoHS Compliant Down Converter 1500 -- 2400 MHz Features * * * * * * * * * * * LNA Mixer integration Typical conversion gain of 7 dB Typical Two-Tone IM Ratio of 50 dBm LO Drive-Level: +13 dBm Low Cost / High Performance 50 ohm Nominal Impedance Lead-Free QSOP-16 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of SA65-0003 MAIA-007495-000100 V1 Functional Block Diagram Description M/A-COM's MAIA-007495-000100 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 0.5micron gate length GaAs MESFET process. Both die feature full passivation for increased performance and reliability. 1. See "External Circuiting Parts" on Sheet 3 for the values of the external components.

For IP3 measurements, RFIN = -24 dBm, this low RF IN level gets amplified through the LNA. For IP3 measurements, RFIN2 = RFIN1 + 10 MHz, LO = RFIN1--140 MHz. For IP3 measurements, IP3 = IMR/2 + PIN. RF IN to IF Isolation is typically 0 dB. Reverse Isolation is measured from IF to RFIN with the IF at -10 dBm, LO at +13 dBm. The amplifier has a normal gain of 12.5 dB, 3V bias and 14.0 dB, 5V bias.

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 |mFRF - nFLO|, RF = -29 dB RF = 1850 MHz LO = 1710 MHz External Circuitry Parts 15 Part C1 C2 C3 L1 L2 L3 R1 R2 R3 Value 47 pF 47 pF 3.3 pF 3.9 nH 3.0 nH 12 nH See Note 16 5.1 k Ohms 330 Ohms Purpose DC Block By-pass LO Port Matching Network Tuning LO Port Matching Network RF Choke Optional Current Control DC Return LO Port Matching Network 15.
