MD-/MDS-148 Double-Balanced Mixer, 10 - 1500 MHz Features V 3.00 FP-2 (MD-148) Fully Hermetic Package 1 dB Compression Point: +5 dBm Conversion Loss: 6 dB Typical Midband LO-RF/LO-IF Isolation: 40 dB Typical Midband Impedance: 50 Ohms Nominal Maximum Input Power: 300 mW Max, Derated to 85°C @ 3.2 mW/°C n X Port Current: 50 mA Max. n MIL-STD-883 Screening Available n n n n n n Description Transformers convert the LO and RF paths to balanced lines connecting to a medium barrier, Schottky diode ring quad. These transformers help provide excellent isolation between ports. Conversion loss is low. The direct connection of the IF port to the diode quad allows these mixers to be used as phase detectors and bi-phase modulators.
