HMC373LP3 / 373LP3E v04.1119 GaAs PHEMT MMIC LOW NOISEAMPLIFIER w/ BYPASS MODE, 700 - 1000 MHzEvaluation Board Circuit T M S - E IS O N W LO - S R IE Application Circuit LIF P M A Note 1: Choose value of capacitor C1 for low frequency bypassing. A 0.01 µF ±10% capacitor is recommended. Note 2: Pin 4 (Vctl) is the DC ground return for the circuit. The LNA is in the high gain mode when a short circuit is introduced to this pin through an external switch. The LNA is in bypass mode when an open circuit is introduced. For the data presented, switching is done through a two position DIP switch (J5) in series with a 2 Ohm resistor (to account for the Ron of an electrical switch). Note 3: L1, L2 and C1 should be located as close to pins as possible. For price, delivery, and to place orders: Analog Devices, Inc., One Technology Way, P.O.
