n

GENERAL DESCRIPTION

NJG1509F is a SPDT switch GaAs MMIC which features
low loss, high isolation and low operating voltage, and
ideally suitable for the T/R switch of digital wireless phone
handsets.

This switch is operated in the wide frequency range from
50MHz to 3GHz at low operating voltage from +2.5V with

very small MTP6 package.

APPLICATION CIRCUIT 1: Single control signal operation by using C-MOS inverter.

[1]Please connect bypass capacitors to the supply terminal of the C-MOS inverter.

[2]In order to stabilize input impedance of inverter, please pull down using 510KΩ

resister from the input terminal of the C-MOS inverter to the ground plane.

[1]External capacitors should be connected to the input and output RF terminals (P1,

P2, PC) to block the DC current. The above example is a circuit at 900MHz. Please
select the capacitors value suitable for actual frequency from 10pF to 1000pF.

[2]Decoupling capacitors should be connected to the control terminals (V

CTR1

, V

CTR2

as close as possible. The values of these capacitors should be selected from 5pF
to 100pF range. Please consider that these values are very effective to switching
time (Larger capacitor gives longer switching time).

[3]In order to keep good isolation characteristics, the grand terminal (5pin) should be

connected to the ground pattern with wide width as close as possible, and
though-hole in the ground plane should also be placed as close as possible.
