2) Mixercircuit This is a double-balanCe mixer having small leak of local oscillation signal. The RF signal is input to Pins 5 and 6. In normal use, the signal is input to orie pin while the other pin is connected to GND via decoupling capacitor. In lhis case, if the capacitor value tor g rounding is smaller (6 pF for the example oi the Electrical Characteristics Measurament Circuit), the conversion gain has the t)etter frequency characteristics.
