ATEK564 Block Diagram
The ATEK564 is a 5 to 22 GHz wideband GaAs pHEMT MMIC driver amplifier designed for radar, SATCOM, SDR, and Electronic Warfare transceivers. Operating from a +5V supply, it delivers 22-26 dB gain, +21 dBm P1dB, and an OIP3 exceeding +30 dBm.For low-power applications, it can operate at +3V for increased gain at reduced output levels. Supplied as a bare die, the device minimizes external components by integrating 50-ohm matched RF ports, internal DC blocks, and a self-bias configuration that requires only two external decoupling capacitorsThe ATEK564 is supplied as a bare MMIC die and has outstanding drive/linearity for a wide range of radar, SATCOM, SDR, test instrument, & EW/ECM transceiver applications. MMICs are available from stock.
