HSMS-8202-BLKG

RF Diode Overview

The HSMS-8202-BLKG is a surface-mount microwave Schottky mixer diode manufactured by Broadcom Limited. It is designed for X/Ku-band applications, specifically optimized for operation between 10 and 14 GHz. The device utilizes a plastic SOT-143 package configuration. Key electrical specifications include a breakdown voltage of 4 V at 10 µA reverse current, a total capacitance of 0.26 pF at 0 V and 1 MHz, and a dynamic resistance of 14 Ω at 5 mA forward current. The typical conversion loss is 6.3 dB at 12 GHz with 1 mW local oscillator power. The component supports a maximum junction temperature of +150°C and features lead-free construction.

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The -BLKG suffix indicates bulk packaging, while -TR1G and -TR2G denote tape and reel options with 3K and 10K piece quantities respectively. Ensure compatibility with automated placement equipment if selecting reel variants. Confirm that the component meets RoHS standards as indicated by the lead-free designation.

RF Diode Selection Notes

Select this component when designing mixers for the 10-14 GHz frequency range requiring low conversion loss. The HSMS-8202 offers matched characteristics suitable for balanced or single-diode configurations. Consider the SOT-143 package dimensions for PCB layout constraints. Verify that the 4 V peak inverse voltage rating aligns with the circuit's operational requirements.

RF Diode Part Context

This part belongs to the HSMS-8101/8202/8207/8209 family of surface mount microwave Schottky mixer diodes. These devices share similar core electrical parameters but may differ in specific performance metrics or package markings. The HSMS-8202 is distinctively identified by its lead code 2 and specific RF parameter tolerances within this product line.

RF Diode Replacement Considerations

The HSMS-8101, HSMS-8207, and HSMS-8209 are electrically similar components within the same datasheet. They share identical breakdown voltage, capacitance, and dynamic resistance values. Substitution should be verified against specific application requirements such as conversion loss tolerance and package marking preferences.
