Note

Function and Application

Internal Equivalent Circuit

N.C.

–

This pin is not connected to internal

circuit. This pin should be opened

or grounded.

–––––––––––––––––

RFout

–

1.75

RF output pin. This pin is emitter

follower which is low impedance

output port. This pin can be easily

matched to 50

Ω impedance using

external coupling and decoupling

capacitors.

External

N.C.

–

These pins are not connected to

internal circuit. These pins should

be opened or grounded.

–––––––––––––––––

VCC

2.7 to 4.0

–

Supply voltage pin for RF output

buffer.

–––––––––––––––––

Fil1

–

2.76

Fil2

–

2.76

External inductor and capacitor can

supress harmonics spurious of LO1

frequency.

LC value should be determined

according to LO1 input frequency

and suppression level.

External

GND

–

Ground pin for modulator, up-

converter and AGC circuits. This pin

should be grounded with minimum

inductance. Form the ground

pattern as widely as possible to

minimize ground impedance.

–––––––––––––––––

Note Pin Voltages are measured on VCC = 3.0 V.
