HMJ7 The Communications Edge ™ High Dynamic Range FET Mixer Product Features • +34 dBm IIP3 • 60 dBc Spurious Rejection in IF • • • • • • Band RF 1000-2000 MHz LO 1000-2000 MHz IF 10-1000 MHz +21 dBm LO Drive Level +5V Bias (40 mA) Low Cost Surface Mount J-Lead Package Functional Diagram Product Description The HMJ7 is a high dynamic range, GaAs FET mixer. This active broadband mixer realizes a typical third order intercept point of +34 dBm at an LO drive level of +21 dBm. The HMJ7 also provides excellent suppression of spurious intermodulation products, greater than 60 dBc. The HMJ7 comes in a low cost, J-Lead package. The combination of high dynamic range and spurious suppression, makes the HMJ7 an ideal choice for CATV headend transmission equipment and other applications requiring a broadband mixer in the 1000 MHz to 2000 MHz frequency range. 22 21 2019 18171615 1413 12 1 2 3 4 5 6 7 8 9 10 11 Function Pin No. Function Pin No. Ground 1 Ground 12 IF 2 LO 13 Ground 3-9 Ground 14-20 +5V DC 10 RF 21 Ground 11 Ground 22 Specifications Parameter Frequency Range: RF LO IF SSB Conversion Loss Noise Figure Isolation: LO-RF LO-IF RF-IF IIP3 Return Loss: RF Port LO Port IF Port Spurious Rejection Input P1dB LO Drive Level DC Current at +5V Bias Units Minimum MHz MHz MHz dB dB 1000 1000 10 dB dB dB dBm 21 24 Typical 8.5 10.5 30 dB dB dB dBc dBm dBm mA Maximum 2000 2000 1000 9.5 24 30 24 34 10 5 14 60 23 21 40 Condition RF = 1018 MHz (0dBm) 60 Test conditions unless otherwise stated: RF = 1018 MHz (-10 dBm), LO = 1017 MHz (21 dBm), IF = 50-860 MHz and 25˚C.
