This port is connected with PC port by controlling 4th pin (VCTL(H)) to 2.5~6.5V and 6th pin(VCTL(L)) to -0.2~+0.2V. An external capacitor is required to block the DC bias voltage of internal circuit. (50~100MHz:0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF) Ground terminal. Please connect this terminal with ground plane as close as possible for excellent RF performance. RF port. This port is connected with PC port by controlling 6th pin (VCTL (H)) to 2.5~6.5V and 4th pin(VCTL(L)) to -0.2~+0.2V. An external capacitor is required to block the DC bias voltage of internal circuit. (50~100MHz:0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF) Control port 2. The voltage of this port controls PC to P1 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 6th pin have to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range. Common RF port. In order to block the DC bias voltage of internal circuit, an external capacitor is required. (50~100MHz:0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF) Control port 1. The voltage of this port controls PC to P2 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 4th pin have to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range. -3- NJG1600KB2 nELECTRICAL CHARACTERISTICS (0.1~3.0GHz, with application circuit, without DC Blocking Capacitor, Losses of external circuit are excluded) PC-P1 Insertion Loss vs. Frequency (VCTL=3.0V/0V) 0.0 PC-P2 Insertion Loss vs. Frequency (VCTL=3.0V/0V) 0.0 -0.2 -0.2 Insertion Loss (dB) Insertion Loss (dB) -0.4 -0.4 -0.6 -0.6 -0.8 -0.8 -1.0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 -1.0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 Frequency (GHz) Frequency (GHz) PC-P1 Isolation vs. Frequency (VCTL=3.0V/0V) 0.0 0.0 PC-P2 Isolation vs. Frequency (VCTL=3.0V/0V) -10.0 -10.0 Isolation (dB) -20.0 Isolation (dB) 0.5 1.0 1.5 2.0 2.5 3.0 -20.0 -30.0 -30.0 -40.0 -40.0 -50.0 0.0 -50.0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 Frequency (GHz) Frequency (GHz) PC-P1 VSWR vs. Frequency (VCTL=3.0V/0V,P1 port) 2.0 2.0 PC-P2 VSWR vs. Frequency (VCTL=3.0V/0V,P2 port) 1.8 1.8 VSWR 1.6 1.4 VSWR 0.5 1.0 1.5 2.0 2.5 3.0 1.6 1.4 1.2 1.2 1.0 0.0 1.0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 Frequency (GHz) Frequency (GHz) -4- NJG1600KB2 nELECTRICAL CHARACTERISTICS (Application circuit (Parts list 2)) Insertion Loss vs. Input Power (PC-P1 ON,f=2.5GHz) 0.0 Input Power vs. Output Power,ICTL (VCTL=3.0V/0V,f=2.5GHz) 30.0 VCTL(H)=2.3V VCTL(H)=2.5V VCTL(H)=2.7V 20 Output Power (dBm) Insertion Loss (dB) -0.5 25.0 VCTL(H)=3.5V VCTL(H)=5V VCTL(H)=6.5V 15 -1.0 20.0 10 -1.5 VCTL(H)=2.3V VCTL(H)=2.5V VCTL(H)=2.7V VCTL(H)=3.0V VCTL(H)=3.5V VCTL(H)=5V VCTL(H)=6.5V 15.0 5 -2.0 10.0 15.0 20.0 25.0 30.0 10.0 10.0 15.0 20.0 25.0 0 30.0 Input Power (dBm) Input Power (dBm) PC-P1 Insertion Loss vs. Ambient Temperature (PC-P1 ON, f=2.5GHz, Pin=18dBm) 0.0 PC-P2 Isolation vs. Ambient Temperature (PC-P1 ON, VCTL=3.0V/0V, f=2.5GHz, Pin=18dBm) -10 Insertion Loss (dB) -0.2 Isolation (dB) -15 -0.4 -0.6 VCTL=2.5V VCTL=2.7V VCTL=3.0V VCTL=5.0V VCTL=6.5V -20 -0.8 -1.0 -50 0 50 o 100 -25 -50 0 50 o 100 Ambient Temperature ( C) Ambient Temperature ( C) PC-P1 P-1dB vs. Ambient Temperature (PC-P1 ON, f=2.5GHz) 30 20 ICTL vs. Ambient Temperature (PC-P1 ON, f=2.5GHz, Pin=18dBm) VCTL=2.5V VCTL=2.7V VCTL=3.0V VCTL=5.0V VCTL=6.5V 28 15 P-1dB (dBm) 26 ICTL (uA) 10 24 VCTL=2.5V VCTL=2.7V VCTL=3.0V VCTL=5.0V VCTL=6.5V 5 22 20 -50 0 50 o 100 0 -50 0 50 o 100 Ambient Temperature ( C) Ambient Temperature ( C) -5- Control Current (uA) VCTL(H)=3.0V NJG1600KB2 nAPPLICATION CIRCUIT Zo=50 P1 C2 2 Zo=50 P2 C3 NJG1600KB2 3 4 5 R1 C5 VCTL2 (2.7V/0V) 1 6 C4 C1 Zo=50 PC VCTL1 (0V/2.7V) nRECOMMENDED PCB DESIGN (TOP VIEW) PCB SIZE=19.4x14.0mm PCB:FR4,t=0.5mm C3 P2 C5 C2 C4 P1 STRIPLINE WIDTH=1.0mm CAPACITOR: size 1005 R1 VCTL2 C1 PC VCTL1 nPARTS LIST No. C1~C3 C4,C5 Parts list 1 f=0.1~0.5GHz 1000pF 1000pF Parts list 2 f=0.5~2.0GHz 56pF 1000pF PRECAUTIONS [1] The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC.
