Diode Bridge 10A, 200V by International Rectifier
International Rectifier p/n 100JB2L bridge rectifier. These are rated at 10 Amps, 200 Volts. A mounting hole is provided to fasten them down so they wont move under load. Attachment may be made thru soldering or by push-on terminals. 1" sq x 3/8 (or so) high.
04S002 Unit Price : $1.25

STM1645-30 RF Power Module
SGS Thompson is the maker of these microwave rf amplifier modules. They are designed for satellite communications applications. The STM1645-30 is rated for use in the 1625 to 1665Mhz range. A measly 10mW input drives the output to 30 Watts KOWABUNGA!!!!. The device operates on 30VDC and must be heatsinked or the smoke will escape.
