| HMC342LC4 v00.1104 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 13 - 25 GHz 5 AMPLIFIERS - SMT Typical Applications The HMC342LC4 is ideal for: * Point-to-Point Radios * Point-to-Multi-Point Radios & VSAT * Test Equipment & Sensors * Military End-Use Features Noise Figure: 3.5 dB Gain: 22 dB Single Positive Supply: +3.0 V @ 43 mA 50 Ohm Matched Input/Output RoHS Compliant 4x4 mm SMT Package Functional Diagram General Description The HMC342LC4 is a GaAs PHEMT MMIC Low Noise Amplifier housed in a leadless 4x4 mm RoHS compliant SMT package. Operating from 13 to 25 GHz, the amplifier provides 22 dB of gain and +19 dBm of output IP3 from a single +3.0V supply. The low noise figure performance of 3.5 dB is ideal for recieve and transmit pre-driver applications. The RF I/Os are DC blocked and matched to 50 Ohms for ease of use. The HMC342LC4 allows the use of surface mount manufacturing techniques and requires no external matching components.

The circuit board used in this application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
