The RF signal is input through external matching circuit. Terminal for the bypass capacitor of LNA. The bypass capacitor C1 shown in application circuit, should be connected to this terminal as close as possible. Ground terminal(0V) IF signal output terminal. The IF signal is output though external matching circuit's connected to this terminal. Please connect inductance L8 and power supply as application circuit since it is also the terminal of Mixer power supply. Power supply terminal for local amplifier. Please connect R1 and L10 to this terminal shown in the application circuit as close as possible. Local signal input terminal of local amplifier. The local signal input to Local Amplifier through external matching circuit. Ground terminal(0V) RF signal input terminal of Mixer. The RF signal from LNA is sent to Mixer through matching circuit. Ground terminal(0V) Signal output terminal of LNA. The RF signal from LNA is output through external matching circuit connected to this terminal. Please connect inductance L4 and power supply shown in application circuit, since it is also the terminal of LNA power supply. 10 LNAOUT CAUTION 1) Ground terminal (No.3, 7, 9) should be connected to the ground plane as short as possible. -4- NJG1704V nTYPICAL CHARACTERISTICS (LNA+MIXER, fLO=690MHz) Conversion Gain , Noise Figure vs. RF Frequency 30 2 30 28 Conversion Gain , Noise Figure vs. LO Power 4.5 Conversion Gain (dB) Gc Conversion Gain (dB) 28 1.9 Gc 4 3.5 3 2.5 Noise Figure (dB) 26 24 22 20 18 26 1.8 NF 24 1.7 NF 2 1.5 1 22 1.6 20 780 800 820 840 860 880 900 1.5 920 16 -40 -30 -20 -10 0 10 RF Frequency (MHz) Condition fIF=130MHz PRF=-46dBm PLO=-10dBm VLNA=VMIX=VLO=2.7V LO Power (dBm) Condition fIF=130MHz fRF=820MHz, PRF=-46dBm fLO=690MHz VLNA=VMIX=VLO=2.7V Output-IP3 , Input-IP3 vs. LO Power 15 -8 OIP3 10 -12 OIP3 (dBm) IIP3 5 -16 0 -20 -5 -40 -24 -30 -20 -10 0 10 LO Power (dBm) Condition fIF=130MHz fRF1=820.0MHz, PRF=-42dBm fRF2=820.1MHz fLO=690MHz VLNA=VMIX=VLO=2.7V OIP3= 3IF-IM3 2 3IF-IM3 IIP3= -Gc 2 @PRF=-42dBm IIP3 (dBm) -5- Noise Figure (dB) NJG1704V nTYPICAL CHARACTERISTICS (LNA+MIXER, fLO=690MHz) RF IN IMPEDANCE LOCAL IN IMPEDANCE Condition VLNA=2.7V VMIX=VLO=2.7V Marker1: 810MHz Marker2: 850MHz Marker3: 885MHz Condition VLNA=2.7V VMIX=VLO=2.7V Marker1: 680MHz Marker2: 720MHz Marker3: 755MHz IF OUT IMPEDANCE Condition VLNA=2.7V VMIX=VLO=2.7V -6- NJG1704V nTYPICAL CHARACTERISTICS (LNA+MIXER, fLO=690MHz) Conversion Gain , Noise Figure vs. V ,V ,V LNA MIX LO 29 3.5 15 Output-IP3 , Input-IP3 vs. V ,V ,V LNA MIX LO -10 Conversion Gain (dB) 28 27 Gc 3 2.5 14 OIP3 IIP3 -12 Noise Figure (dB) OIP3 (dBm) 26 25 NF 2 1.5 12 -16 11 -18 24 23 1.5 1 0.5 5.5 10 9 1.5 -20 -22 5.5 2 2.5 3 3.5 4 4.5 5 2 2.5 3 3.5 4 4.5 5 V LNA ,V MIX ,V LO (V) V LNA ,V MIX ,V LO (V) OIP3= 3IF-IM3 2 Condition fIF=130MHz fRF=820MHz, PRF =-46dBm fLO=690MHz, PLO=-10dBm Condition fIF=130MHz fRF1=820.0MHz, PRF=-42dBm fRF2=820.1MHz fLO=690MHz, PLO=-10dBm 3IF-IM3 IIP3= -Gc 2 @PRF=-42dBm IF , IM3 vs. RF Power 20 10 5 0 IF vs. RF Power IF 0 IF , IM3 (dBm) IF (dBm) -20 -5 -10 -15 -20 -40 IM3 -60 -80 -50 -40 -30 -20 -10 0 -25 -50 -40 -30 -20 -10 0 RF Power (dBm) Condition fIF=130MHz fRF1=820.0MHz fRF2=820.1MHz fLO=690MHz,PLO=-10dBm VLNA=VMIX=VLO=2.7V RF Power (dBm) Condition fIF=130MHz fRF=820MHz fLO=690MHz,PLO=-10dBm VLNA=VMIX=VLO=2.7V -7- IIP3 (dBm) 13 -14 NJG1704V nTYPICAL CHARACTERISTICS (LNA+MIXER, fLO=690MHz) Conversion Gain , Noise Figure vs. Temperature 31 3 15 30 29 2.5 14 Output-IP3 , Input-IP3 vs. Temperature -11 OIP3 Conversion Gain (dB) -12 Gc NF OIP3 (dBm) 2 Noise Figure (dB) 13 -13 28 27 1.5 1 IIP3 12 -14 26 25 -50 0.5 0 100 11 -15 0 50 o 10 -50 0 50 o -16 100 Temperature ( C) Condition fIF=130MHz fRF=820MHz, PRF=-46dBm fLO=690MHz, PLO=-10dBm VLNA=VMIX=VLO=2.7V Temperature ( C) Condition fIF=130MHz fRF1=820.0MHz, PRF=-42dBm fRF2=820.1MHz fLO=690MHz VLNA=VMIX=VLO=2.7V OIP3= 3IF-IM3 2 3IF-IM3 IIP3= -Gc 2 @PRF=-42dBm I 7 6 LNA ,I I MIX ,I LO vs. Temperature MIX (mA) 5 4 3 2 1 0 -50 LO LNA ,I MIX ,I I LNA I I LO 0 50 o 100 Temperature ( C) Condition PRF=OFF PLO=OFF VLNA=VMIX=VLO=2.7V -8- IIP3 (dBm) NJG1704V nTYPICAL CHARACTERISTICS (LNA+MIXER, fLO=690MHz) RF IN -
