GaAs PHEMT MEDIUM POWER AMPLIFIER, 17 - 24 GHz Pin Descriptions
Pin Number Function Description Interface Schematic T These pins are not connected internally; however, all data 1, 5 - 8, 10 - 14, M N/C shown herein was measured with these pins connected to 18, 20, 22, 24 RF/DC ground externally. Package bottom has an exposed metal paddle that must 2, 4, 15, 17 GND also be connected to RF/DC ground. S - S R This pin is AC coupled 3 RFIN IE and matched to 50 Ohms. LIF Gate control for amplifier. Adjust to achieve Id of 250 mA. P Please follow “MMIC Amplifier Biasing Procedure” 9 Vgg Application Note. External bypass capacitors of 100 pF, M 1000 pF and 2.2 µF are required. R A This pin is AC coupled E 16 RFOUT and matched to 50 Ohms. W O Power Supply Voltage for the amplifier. External bypass 23, 21, 19 Vdd1, Vdd2, Vdd3 capacitors of 100 pF, 1000pF, and 2.2 µF are required. R & P A
