HMJ7-PCB

High Dynamic Range FET Mixer HMJ7 The Communications Edge TM Product Information Product Features x +34 dBm IIP3 x 67 dBc 2x1 Spur Rejection in IF Band x RF 1000 - 2000 MHz x LO 1000 - 2000 MHz x IF 10 - 1000 MHz x +5V Bias (40 mA) x +21 dBm LO Drive Level x SMT J-Lead Package 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, 22-pin 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.

Test conditions unless otherwise noted: 25 ºC, RF = 1018.75 MHz @ 0 dBm, LO = 21 dBm, IF = 50, 650, 860 MHz in a high-side LO configuration. 2. The 2x1 spur is tested where the IM spur = 2 * RF input – LO, where RF input = 1018.75 MHz @ -5 dBm, LO = 1568.75 & 1668.75 MHz @ 21 dBm, IM spur = output frequency. The IM spur level is specified in dBc with respect to the desired IF frequency calculated: IF output = LO - RF input.

Notes Land Pattern / Mounting Configuration 1. Ground vias are critical for thermal and RF grounding considerations. 2. A minimum of 36 ground vias are required for 14 mil FR4 boards. 3. If your PCB design rules allow, ground vias should be placed under the land pattern for better RF performance. Otherwise ground vias should be placed as close to the land pattern as possible. 4. Trace width depends on the PCB material.
