Circuit Description The pins RF (7) and RF (8) are low resistance inputs of the base coupled difference stage. The resistor of at least 200 Ω may be connected between pins 7 and 6 (ground) and between 8 and 6 to increase the currents (max. 4 mA per pin) and thus the conversion transductance. The pins LO (4) and LO (5) are the local oscillator inputs of the mixer. The connections to the mixer inputs may be symmetrical or asymmetrical coupled, capacitive or inductive coupled. The mixer outputs MO (1) and MO (2) are high impedance open-collector outputs for frequencies up to 2 GHz.
