HMC551LP4 / 551LP4E v02.1210 Mixers - SINGLE & DOUBLE BALANCED - SMT 10 GaAs MMIC MIXER w/ INTEGRATED LO AMPLIFIER, 0.8 - 1.2 GHz Typical Applications Features The HMC551LP4 / HMC551LP4E is ideal for Wireless Infrastructure Applications: Input IP3: +27 dBm • Cellular / 3G Infrastructure LO to RF Isolation: 27 dB • Base Stations & Repeaters Low Conversion Loss: 8 dB • GSM, CDMA & W-CDMA Single Supply: +5V @ 62 mA • PLMR & ISM 24 Lead 4x4mm QFN Package: 9 mm² Functional Diagram General Description Low Input LO Drive: -4 to +4 dBm The HMC551LP4 & HMC551LP4E are high linearity, double balanced Converter ICs that operate from 0.8 to 1.2 GHz and deliver a +27 dBm input third order intercept point. The LO amplifier output and high dynamic range mixer input are positioned so that an external LO filter can be placed in series between them. The converter provides 27 dB of LO to RF isolation and is ideal for upconverter and downconverter applications. The IC operates from a single +5V supply consuming 62 mA of current and accepts a LO drive level of -4 to +4 dBm. The design requires no external baluns and supports IF frequencies between DC and 300 MHz. The HMC551LP4(E) are pin for pin compatible with the HMC552LP4(E) which operate from 1.6 to 3.0 GHz.

An off chip DC blocking capacitor is required. 2, 6 - 9, 11 - 17, 19 - 24 N/C No connection. These pins may be connected to RF ground. Performance will not be affected. 3 BIAS Power supply for the LO amplifier Bias resistor is required . Three external bypass capacitors are recommended for optimum performance, as illustrated in the application circuit. 4 GND Backside of package has exposed metal ground paddle that must also be connected to ground. 5 LO This pin is DC coupled and matched to 50 Ohms from 0.8 to 1.2 GHz. An off chip DC blocking capacitor is required. 10 IF This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary IF frequency range. For operation to DC, this pin must not source/ sink more than 18 mA of current or die non-function and possible die failure will result. 18 RF This pin is DC coupled and matched to 50 Ohms.
