| High Dynamic Range FET Mixer HMJ8 Product Features x +37 dBm IIP3 x No External Matching Elements Required Product Description The HMJ8 is a high dynamic range GaAs FET mixer. This active FET mixer realizes a typical third order intercept point of +37 dBm at an LO drive level of +18 dBm. The HMJ8 comes in a low cost, 18-pin J-Lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in communication systems.

HMJ8 US PAT. 5732345 mm inch ESD Information ESD Rating: Value: Test: Standard: ESD Rating: Value: Test: Standard: Class 2 Passes at 2000 V Human Body Model (HBM) JEDEC Standard JESD22-A114 Class IV Passes at 2000 V Charged Device Model (CDM) JEDEC Standard JESD22-C101 Mounting Config. Notes 1. Ground vias are critical for thermal and RF grounding considerations. 2. A minimum of 28 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.
