HMC635LC4 v02.0218 AMPLIFIERS - DRIVER & GAIN BLOCK - SMT GaAs PHEMT MMIC DRIVER AMPLIFIER, 18 - 40 GHz Typical Applications Features The HMC635LC4 is ideal for: Gain: 18.5 dB [2] * Point-to-Point Radios P1dB: +22 dBm [2] * Point-to-Multi-Point Radios & VSAT Output IP3: +27 dBm * LO Driver for Mixers Saturated Power: +23.5 dBm @ 15% PAE [2] * Military & Space Supply Voltage: +5V @ 280 mA 50 Ohm Matched Input/Output 24 Lead Ceramic 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC635LC4 is a GaAs PHEMT MMIC Driver Amplifier die which operates between 18 and 40 GHz. The amplifier provides 18.5 dB of gain, +27 dBm Output IP3, and +22 dBm of output power at 1 dB gain compression, while requiring 280 mA from a +5V supply. Ideal as a driver amplifier for microwave radio applications, or as an LO driver for mixers operating between 18 and 40 GHz, the HMC635LC4 is capable of providing up to +23.5 dBm of saturated output power at 15% PAE. The amplifier's I/Os are DC blocked and internally matched to 50 Ohms making it ideal for integration into Multi-Chip-Modules (MCMs).

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 Analog Devices upon request. AMPLIFIERS - DRIVER & GAIN BLOCK - SMT Evaluation PCB [2] Circuit Board Material: Rogers 4350 or Arlon 25FR [3] Due to the very high frequency operation of this product a custom LC4 PCB footprint and solder stencil are required for this design. Performance shown in this data sheet was produced using this custom footprint. DO NOT USE Hittite's standard LC4 footprint. Please contact Applications for details.
