Single Diode Configuration: HIPAX PIN diode series is designed for usage in switch and attenuator applications requiring high power handling and low distortion. HIPAX PIN diodes incorporate a fully passivated PIN diode chip resulting in an extremely low reverse bias leakage current. The semiconductor technology utilized in the HIPAX family draws on MACOM's substantial experience in PIN diode design and wafer fabrication. The result is a device which has a thick I-region and long carrier lifetime while maintaining low series resistance and capacitance values. The chip of the HIPAX PIN diode is enclosed in a rugged ceramic package and is full face bonded to refractory metal pins on both the anode and cathode. The result is a low loss PIN diode with low thermal resistance due to symmetrical thermal paths. The parts are offered in either axial leaded or Metal Electrode Leadless Faced (MELF) surface mount packages that have a rectangular outline. These rectangular SMQ PIN diodes are designed for high volume tape and reel assembly. This user friendly package design makes automatic pick and place, indexing and assembly extremely easy. The parallel flat surfaces are suitable for most key jaw or vacuum pick-up techniques. All solderable surfaces are tin plated and compatible with industry standard reflow and vapor phase soldering processes. HIPAX PIN diodes are designed for use in a wide variety of switch and attenuator applications from HF through UHF frequencies and at power levels above 1kW, CW. The internal chip as well as each diode assembly has been comprehensively tested and characterized to ensure predictable and repeatable performance.
