Final Datasheet (October 1st, 2002) R3 R4 10 GaAs MMIC CMH0819 CMH0819 Application Notes DC Biasing Minimum LO Power for Proper Biasing For proper biasing of the CMH0819 CMH0819, a minimum LO input power is required. If the part is turned ON without any LO drive applied all currents will be extremely high. The minimum LO required is 7 dBm (-10 dBm in Cellular). Operation with LO input powers below the minimum value causes the current to increase rapidly in all amplifier stages. For higher LO input power levels the current decreases slightly but stays relatively constant over a wide range of LO powers. Proper matching of the LO amplifier is also important to achieve the lowest current consumption and to minimize the required LO input power. Tuning LO and IF Amplifiers The CMH0819 CMH0819 can be tuned to utilize either high or low side LO frequencies and allows a wide range of IF frequencies. Depending on the chosen frequency plan the off chip components for the LO and IF amplifiers will need to be optimized. LO Amplifer: L3 is critical for setting the minimum current and to achieve the constant DC current over the cellular operating band. For operation with PCS LO frequencies lower than identified in the application circuits additional inductance may be necessary in series with pin 1. L4 should be selected to optimize the LO input match for PCS operation. IF Amplifiers: Components L8 and C13 form the input match for the IF amplifiers and will vary depending on the chosen IF frequency. C12 is a DC block. The IF impedance at the mixer output is nearly 50 Ohm, so the IFA can be initially tuned on its own in 50 Ohms connecting L8 to a 50 Ohm test port. This match should be optimized for CDMA mode but some compromise is needed to ensure good performance in AMPS mode. Output matching components shown in the application circuit provide a transformation for a 50 Ohm load impedance. The output impedance for the CDMA IFA (looking into pin 22) is approximately (900 - j*800) Ohms at 130 MHz. For the AMPS IFA the impedance is approximately (142-j*40) at 130 MHz. CDMA Mixer Gain Adjustment The CDMA (CEL and PCS) Mixer gain can be adjusted by changing the source feedback inductor L7 for the IFA. Higher inductance will give lower downconverter gain and typically improve the IIP3. LNA Matching Inductors L1 and L2 are critical for setting the Noise Figure of the LNAs. A high Q, wire wound inductor (e.g. Coilcraft) is recommended to achieve minimum NF. Control Line Impedances Control Line Impedances are greater than 1 Meg Ohm when Vdd is ON and ~ 25 K when Vdd is OFF.
