HMC785LP4E v02.0909 MIXERS - DOWNCONVERTERS - SMT 8 BiCMOS MIXER W/ INTEGRATED LO AMPLIFIER, 1.7 - 2.2 GHz Typical Applications Features The HMC785LP4E is Ideal for: High Input IP3: +38 dBm • Cellular/3G & LTE/WiMAX/4G 8 dB Conversion Loss @ 0 dBm LO • Basestations & Repeaters Optimized for Low Side LO Input • GSM, CDMA & OFDM Adjustable Supply Current • Transmitters and Receivers 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC785LP4E is a high dynamic range passive MMIC mixer with integrated LO amplifier in a 4x4 SMT QFN package covering 1.7 to 2.2 GHz. Excellent input IP3 performance of +38 dBm for down conversion is provided for 3G & 4G GSM/CDMA applications at an LO drive of 0 dBm. With an input 1 dB compression of +26 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 8 dB typical. Up to 300 MHz IF frequency response will satisfy GSM/CDMA transmit or receive frequency plans. The HMC785LP4E is optimized for low side LO frequency plans for 1.7 - 2.2 GHz RF Band and is pin for pin compatible with the HMC685LP4E Electrical Specifi cations, TA = +25° C, LO = 0 dBm, Vcc = Vcc1, 2, 3 = +5V, G_Bias = +2.5V * Parameter Min.

These pins may be connected to RF ground. Performance will not be affected. 2, 5, 15, 17 GND Package bottom must be connected to RF/DC ground. 3 RF This pin is matched single-ended to 50 Ohms and DC shorted to ground through a balun. 4 TAP Center tap of secondary side of the internal RF balun. Short to ground with zero Ohms close to the IC. 8, 10, 24 Vcc1, Vcc2, Vcc3 Power supply voltage. See application circuit for required external components. 9 LO_BIAS LO buffer current adjustment pin. Adjust the LO buffer current through the external resistor R9 shown in the application circuit (connect 200 Ohms for nominal operation). This adjustment allows for a trade-off between power dissipation and linearity performance of the converter. 16 LO This pin is matched single-ended 50 ohm and DC shorted to ground through a balun. 19 G_BIAS External bias with a nominal value of 2.5V. See application circuit for recommended external components. G_Bias can be set to between 0 and 5Vdc. This adjustment allows for a trade off between conversion loss and linearity performance of the converter (see figures CG, IP3 vs. G-Bias). The G_bias pin has an internal 15 KOhms resistance to ground and 15 KOhms to Vcc. Internal resistive divider sets 2.5 V for G_bias and can be changed externally. 21, 22 IFN, IFP Differential IF input / output pins matched to differential 50 Ohms. For applications not requiring operation to DC an off chip DC blocking capacitor should be used.
