Key Features
- Dual silicon Schottky mixer diode in series-connected center-tap configuration for balanced and double-balanced mixer circuits operating from X-band to Ku-band (8–18 GHz)
- Ultra-low junction capacitance of 0.26 pF maximizes conversion gain and minimizes insertion loss at millimeter-wave RF frequencies
- Compact SOT-23 3-pin surface-mount package enables chip-scale RF layout with minimal parasitic inductance for microwave PCB and MIC designs
Applications
The HSMS-8202-TR1G is optimized for X-band and Ku-band RF front-end circuits in radar receivers, satellite communication downconverters, and point-to-point microwave link mixers operating between 8 GHz and 18 GHz. Its center-tap dual configuration suits balanced mixer topologies that suppress LO leakage and even-order intermodulation products, improving receiver dynamic range in electronic warfare and instrumentation systems. The SOT-23 package also enables compact phase-shifter and single-sideband modulator designs in phased-array antenna modules.

Frequently Asked Questions
What frequency range does the HSMS-8202-TR1G cover, and which RF applications benefit from this range?
The HSMS-8202-TR1G is specified for X-band to Ku-band operation, covering approximately 8 GHz to 18 GHz. This range spans radar altimeters, weather radars, maritime surveillance radars operating at 9.3 GHz, Ku-band satellite receive LNBs at 10.7–12.75 GHz, and 15–18 GHz point-to-point wireless backhaul links, all of which use Schottky mixer diodes for frequency down-conversion.
How does the 0.26 pF junction capacitance of the HSMS-8202-TR1G affect its performance at 12 GHz?
At 12 GHz, a junction capacitance of 0.26 pF presents a reactance of approximately 51 Ω, which is low enough to allow efficient RF current flow while still being tunable with a short transmission-line stub. Lower capacitance reduces the reactive loading on the mixer circuit, improving conversion loss by 1–2 dB compared to diodes with capacitance above 0.5 pF in the same frequency range.
What is the HSMS-8202-TR1G diode configuration, and why is a center-tap dual arrangement preferred in balanced mixers?
The HSMS-8202-TR1G uses 2 diode elements connected in series with a center-tap output. In a balanced mixer, this configuration cancels LO-to-IF feedthrough by presenting equal and opposite RF voltages to the IF port during each LO half-cycle, improving LO isolation by 20–30 dB compared to single-diode mixers. Even-order distortion products are also suppressed, reducing intermodulation interference in wideband receivers.
Is the HSMS-8202-TR1G available in tape-and-reel form for automated SMT assembly, and what package does it use?
Yes, the TR1G suffix indicates the HSMS-8202 is supplied in tape-and-reel format on a standard 7-inch reel. The package is a 3-pin SOT-23, measuring approximately 2.9 mm × 1.6 mm × 1.1 mm, which is compatible with standard automated pick-and-place equipment and reflow soldering processes at peak temperatures up to 260 °C per J-STD-020.
