TERMINAL INFORMATION

PIN No. SYMBOL DESCRIPTIONS

1 LOIN

Local power input terminal of local amplifier. External matching circuit is required.

2 GND Ground terminal (0V).

3 RFIN RF input terminal of mixer. External matching circuit is required.

4 IFOUT

IF signal output terminal for mixer external matching circuit is required. Please connect mixer power supply through choke inductor (L7) as shown in test circuit.

5 BPC

Optional bypass capacitor terminal for mixer. Please connect optimum capacitor if need for tuning Gc or IP3.

6 VLO

Local amplifier supply terminal. Please place R1 & L5 close to this terminal as shown in test circuit.

NOTE:

1) Ground terminal (2pin) should be connected with ground plane by multiple via holes for good grounding.
