MD-614 Double-Balanced Mixer, 0.7 - 2 GHz Features V 3.00 FP-2 n Fully Hermetic Package n Conversion Loss: 6 dB Typical Midband n Isolation: 25 dB Typical n Impedance: 50 Ohms Nominal n Maximum Input Power: 300 mW Max, Derated to 85C n n @ 3.2 mW/C IF Port Current: 50 mA Max. MIL-STD-883 Screening Available Description Transformers convert the LO and RF paths to balanced lines connecting to a low 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.
