HMJ5 The Communications Edge ™ High Dynamic Range FET Mixer Product Features • +35 dBm IIP3 • No external matching element • • • • • • Functional Diagram Product Description Required RF 40-1000 MHz LO 30-900 MHz IF 5-250 MHz +17 dBm LO Drive Level +3V at 35 mA DC Power Supply Low Cost Surface Mount J-Lead Package The HMJ5 is a high dynamic range, GaAs FET mixer. This active FET mixer realizes a typical third order intercept point of +35 dBm at an LO drive level of +17 dBm. The HMJ5 comes in a low cost, J-Lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in communications systems. 22 21 2019 18171615 1413 12 1 2 3 4 5 6 7 8 9 10 11 D• e E T DA O Driv P U L • dBm 7 1 + Function Pin No. Function Pin No. Ground 1 Ground 12 IF 2 LO 13 Ground 3-9 Ground 14-20 +3V DC 10 RF 21 Ground 11 Ground 22 Specifications Parameter Frequency Range: RF LO IF SSB Conversion Loss SSB Noise Figure Isolation: LO to RF LO to IF IIP3 Return Loss: RF Port LO Port IF Port Input P1dB LO Drive Level DC Current at +3V Bias Units Minimum MHz MHz MHz dB dB 40 30 5 dB dB dBm 20 24 31 Typical 7.5 9.5 dB dB dB dBm dBm mA Maximum Condition 1000 900 250 9.0 28 30 35 RF = 900 MHz (0 dBm) 11.7 6.0 10.9 23 17 35 60 Notes: 1. RF = 905 MHz (-10 dBm) LO 900 (+17 dB) IF = 5 at 25°C. 2. Measured in a 50-ohm system with nominal LO drive in a downconverter application only, unless otherwise specified. 3. LO frequency must be separated from IF frequency by a minimum of 2 MHz (i.e., |FLO - FIF| ≥ 2 MHz).
