MMIC Amplifier HMC599ST89E

January 17, 2011

The HMC599ST89E is a GaAs pHEMT based, Wide Dynamic Range Gain Block MMIC Amplifier which is rated from 50 to 960 MHz and delivers 14 dB gain, +39 dBm output IP3, and noise figure as low as 2 dB. Input and output return losses are excellent at 15 dB or better. The HMC599ST89E can be used as a cascadable 75 Ohm RF or IF gain stage as well as a PA or LO driver with up to +19 dBm output P1dB compression.

This versatile MMIC amplifier exhibits excellent gain and output power stability over temperature, and requires a minimal number of external bias components. The HMC599ST89E is housed in an industry standard RoHS compliant SOT89 package, and can be powered directly from either a +3V or +5V supply.

Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
