HSCH-53xx Series Beam Lead Schottky Diodes for Mixers and Detectors (1-26 GHz) Data Sheet Description Features These beam lead diodes are constructed using a metal- Platinum tri-metal system semiconductor Schottky barrier junction. Advanced High temperature stability epitaxial techniques and precise process control insure Silicon nitride passivation uniformity and repeatability of this planar passivated Stable, reliable performance microwave semiconductor. A nitride passivation layer Low noise figure provides immunity from contaminants which could Guaranteed 7.5 dB at 26 GHz otherwise lead to I drift. R High uniformity Tightly controlled process insures uniform RF The Avago beam lead process allows for large beam characteristics anchor pads for rugged construction (typical 6 gram pull strength) without degrading capacitance. Rugged construction 4 grams minimum lead pull Applications Low capacitance The beam lead diode is ideally suited for use in stripline 0.10 pF max. at 0 V or microstrip circuits. Its small physical size and Polyimide scratch protection uniform dimensions give it low parasitics and repeatable RF characteristics through K-band. The basic medium barrier devices in this family are DC Outline 07 tested HSCH-5310 and -5312. Equivalent low barrier CATHODE devices are HSCH-5330 and -5332. Batch matched GOLD LEADS versions are available as HSCH-5331. 130 (5) 100 (4) 135 (5) The HSCH-5340 is selected for applications requiring 90 (3) guaranteed RF-tested performance up to 26 GHz. The 135 (5) HSCH-5314 is rated at 7.2 dB maximum noise figure at 90 (3) 16 GHz. 225 (9) 310 (12) 225 (9) 200 (8) 250 (10) 170 (7) Assembly Techniques Thermocompression bonding is recommended. Welding or conductive epoxy may also be used. For additional information, see Application Note 979, The Handling 8 Min.
