HMC685LP4 / 685LP4E v04.0110 Mixers - SINGLE & DOUBLE BALANCED - SMT 10 BiCMOS MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 1.7 - 2.2 GHz Typical Applications Features The HMC685LP4(E) is Ideal for: High Input IP3: +35 dBm • Cellular/3G & LTE/WiMAX/4G 8 dB Conversion Loss @ 0 dBm LO • Basestations & Repeaters Optimized for Low Side LO Input • GSM, CDMA & OFDM Upconversion & Downconversion Applications • Transmitters and Receivers Adjustable Supply Current 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC685LP4(E) 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 +35 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 +27 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 8 dB typical. The DC to 500 MHz IF frequency response will satisfy GSM/CDMA transmit or receive frequency plans. The HMC685LP4(E) is pin for pin compatible with the HMC684LP4(E) which is a 700 - 1000 MHz mixer with LO amplifier. Electrical Specifications, TA = +25° C, IF = 200 MHz, LO = 0 dBm, Vcc = Vcc1, 2, 3 = +5V, G_Bias = +2.5V* Icc = 120 mA Nominal Supply Parameter Min. Typ. Max. Icc = 90 mA Icc = 70 mA Typ. Typ.

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 50 Ohm and DC shorted to ground through a balun. 4 TAP Center tap of secondary side of the internal RF balun. Short to ground with a zero ohm 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 270 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. See application circuit for recommended external components. Apply +2.5V for nominal operation at 5V supply voltage. G_Bias can be set to between 0 and 5Vdc. The G_bias pin has an internal 15K ohm resistance to ground. This adjustment allows for a trade off between conversion loss and linearity performance of the converter (see figures CG, IP3 vs. G-Bias). 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.
