HMC1082LP4E v05.1018 GaAs pHEMT MMIC MEDIUMPOWER AMPLIFIER, 5.5 - 18 GHzPin Descriptions Pin Number Function Description Pin Schematic These pins are not connected internally, however all 1, 2, 5, 6, 7, 8, 10, 13, N/C data shown herein was measured with these pins T 14, 17, 18, 19, 21, 23 connected to RF/DC ground externally. M 3 RF IN This pin is DC coupled and matched to 50 Ohms. R - S E These pins and package bottom must be connected to 4, 15 GND W RF/DC ground. O Gate control for amplifier. External bypass capacitors 9 Vgg of 1000pF, 100pF and 2.2uF are required. R & P A E DC bias of diode biased through external resistor used IN 11 Vref for temperature compensation of Vdet. See application circuit. DC voltage representing RF output power rectified by S - L 12 Vdet diode which is biased through an external resistor. See application circuit. R IE RFOUT 16 RF OUT This pin is DC coupled and matched to 50 Ohms. 2.5k Ω LIF P M A Drain bias voltage for amplifier. External bypass capac- 24, 22, 20 Vdd1, Vdd2, Vdd3 itors of 1000pF, 100pF and 2.2uF are required. For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O.
