MASW-001150-1316
HMIC PIN Diode,50W
A PIN diode series-shunt switch element with a unique integrated thermal terminal for dissipating heat in the series diode created by the DC and RF input power. The thermal terminal allows for optimum heat dissipation by providing a direct thermal connection between the series diode and the circuit heatsink while also being electrically isolated. The chip is designed to provide a heat transfer conduit that does not interfere with the PIN diode anode (input) and cathode (output) electrical terminals, especially with respect to RF performance. The chip is fabricated using MACOM's patented HMIC™ process and features silicon pedestals embedded in a low loss, low dispersion glass for low leakage current. The topside is fully encapsulated with silicon nitride and has an additional polymer layer to protect against damage during handling and assembly. This PIN diode series-shunt switch element is particularly advantageous in high average power, 50W, switch applications from 30MHZ – 3GHz. The backside RF, D.C., and thermal I/O ports allow for direct solder re-flow, surface mount, attachment to a micro-strip circuit assembly. The thermal terminal design provides the, power dissipating, series diode a direct connection to the circuit thermal ground for unprecedented heat transfer. The thermal terminal port is electrically isolated from the I/O ports and can be configured as either a reflective or an absorptive switch.
