The number and size of ground via holes in a circuit board is critical for thermal and RF grounding considerations. 2. We recommend that the ground via holes be placed on the bottom of lead pin 2 for better RF and thermal performance, as shown in the drawing at the left side. 2/6 ww.ASB.co.kr March 2004 ASG303 Application Circuit: 900 MHz Typical Performance Frequency Magnitude S21 Magnitude S11 Magnitude S22 Output P1dB Output IP3 1) Schematic 900 MHz 19 dB -16 dB -16 dB 19 dBm 40 dBm 2.8 dB 5V 55 mA L3=33nH RF IN C4=0.1 µF C1=6 pF L1=390 nH L2=22 nH RF OUT R1=11 kΩ Vcc=5V C5= 100 pF C6= 1 µF Noise Figure Supply Voltage Current 50 Ω 7 mm C2=5 pF ASG303 C3=100pF 1) OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 1MHz Gain vs. Temperature 2 Board Layout (FR4, 40x40 mm , 0.8T) 24 22 20 18 16 14 12 10 Frequency = 900MHz -40 -20 0 20 40 60 80 100 S-parameters 0 -5 -10 -15 -20 -25 0 -5 -10 -15 -20 -25 -30 -35 600 700 800 900 1000 1100 1200 8 5Β C 2 5Β C -40Β C 85 Β C 25 Β C -40Β C -30 -35 600 700 800 900 1000 1100 1200 3/6 ww.ASB.co.kr March 2004 ASG303 30 0 -5 -10 -15 -20 -25 10 -30 5 -35 600 700 800 900 1000 1100 1200 25 85 Β C 25 Β C -40Β C 20 15 85 Β C 25 Β C -40Β C 600 700 800 900 1000 1100 1200 OP1 vs. Frequency 28 26 24 22 20 18 16 14 12 800 850 900 950 1000 85 Β C 25 Β C -40Β C Output IP3 vs. Frequency (Pout per tone = 8dBm) 55 55 Output IP3 vs. Tone Power (Frequency = 900MHz) 50 45 85 Β C 25 Β C -40Β C 50 45 85 Β C 25 Β C -40Β C 40 40 35 35 30 30 800 850 900 950 1000 4 5 6 7 8 9 10 11 12 4/6 ww.ASB.co.kr March 2004 Application Circuit: 2000 MHz Typical Performance Frequency Magnitude S21 Magnitude S11 Magnitude S22 Output P1dB Output IP3 1) Schematic 2000 MHz 12.5 dB -24 dB -23 dB 19 dBm 40 dBm 3.3 dB 5V 55 mA L3=22nH C2=0.75 pF RF IN C5=0.1 µF L1=100 nH L2=10 nH R1=11 kΩ Vcc=5 V C6= 100 pF C7= 1 µF Noise Figure Supply Voltage Current C1=1 pF RF OUT 50 Ω 3 mm ASG303 C3=100pF C4=0.5 pF 1) OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 1 MHz.
