| NJG1524APC1 DPDT SWITCH GaAs MMIC nGENERAL DESCRIPTION NJG1524APC1 is a DPDT switch GaAs MMIC. The two same switches are merged into one package and functionally linked. It is useful for switching two circuits in-line. Each switches feature very ow loss, high isolation l and wide frequency coverage from 50MHz to 3GHz at low control voltage of 2.5V. The ultra small & thin FFP16-C1package is adopted. nPACKAGE OUTLINE NJG1524APC1 nFEATURES lSingle low voltage control lLow insertion loss lHigh isolation lHanding power lLow current consumption lUltra small & thin package nPIN CONFIGURATION FFP16 Type (Top View) 16 1 2 3 4 5 6 7 8 15 14 13 +2.5~+6.5V 0.3dB typ.@f=1GHz, PIN=0dBm, each switch 0.5dB typ.@f=2GHz, PIN=0dBm, each switch 42dB typ. @f=2GHz,PC1-PC2 27dB typ.@f=2GHz, PC1-PA1 PC1-PA2, PC2-PB1, PC2-PB2, PA1-PA2, PB1-PB2 20dBm max. @f=2GHz, VCTL=2.7V 16uA typ.@f=2GHz, PIN=10dBm FFP16-C1 (Package size: 2.5x2.5x0.85mm) Pin Connection 1.GND 12 11 10 9 9.GND 10.PC1 11.GND 12.GND 13.PA2 14.VCTL1 2.GND 3.PC2 4.GND 5.PB1 6.NC 7.VCTL1 15.VCTL2 8.PA1 16.PB2 nTRUTH TABLE "H"=VCTL (H), "L"=VCTL (L) VCTL1 VCTL2 PC1 - PA1 PC2 - PB1 PC1 - PA2 PC2 - PB2 H L ON OFF L H OFF ON NOTE: Please note that any information on this catalog will be subject to change. -1- NJG1524APC1 nABSOLUTE MAXIMUM RATINGS (Ta=25C) PARAMETER Input Power Control voltage Power Dissipation Operating Temp.

In order to block the DC bias voltage of internal circuit, an external capacitor is required. RF port B1. This port is connected with PC1 port by controlling VCTL2 to -0.2~+0.2V and VCTL1 to 2.5~6.5V. In order to block the DC bias voltage of internal circuit, an external capacitor is required. No connected terminal. Control port 1. The voltage of this port controls PC1 to PA1/PA2 and PC2 to PB1/PB2 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal to high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of VCTL2 should be set to opposite state. The bypass capacitor should be connected with GND as close as possible for excellent RF performance. RF port A1. This port is connected with PC1 port by controlling VCTL2 to -0.2~+0.2V and VCTL1 to 2.5~6.5V. In order to block the DC bias voltage of internal circuit, an external capacitor is required.

Please choose appropriate capacitance values to the application frequency. [2]To reduce stripline influence on RF characteristics, please locate bypass capacitors (C7, C8) close to each terminal. [3]For good isolation the GND terminal must be placed possibly close to ground place of substrate, and through holes for GND should be placed near by the pin connection. -7- NJG1524APC1 nPACKAGE OUTLINE (FFP16-C1) 1pin INDEX 0.35 2pin INDEX 0.2540.1 0.850.15 0.10 0.30 0.30 2.50.1 0.17 UNIT PCB OVER COAT : mm : Ceramic : Epoxy resin : 15mg 0.50 0.50 0.20 TERMINAL TREAT : Au 0.365 0.27 WEIGHT Cautions on using this product This product contains Gallium-Arsenide (GaAs) which is a harmful material. * Do NOT eat or put into mouth. * Do NOT dispose in fire or break up this product. * Do NOT chemically make gas or powder with this product. * To waste this product, please obey the relating law of your country.
