HDG204-DN-3

RF Transceiver ICS Overview

The HDG204-DN-3 is a System-in-Package (SiP) RF transceiver module designed for Wireless LAN applications. It complies with the IEEE 802.11b/g standards and operates within the 2.4GHz to 2.5GHz frequency range. The module supports a maximum data rate of 54Mbps using modulation schemes including OFDM, CCK, BPSK, QPSK, and 16/64QAM. Key electrical specifications include an output power of 18dBm and a receiver sensitivity of -96dBm. It interfaces via SPI and features two GPIO pins. The device requires a 3.3V supply, drawing 15mA during transmission and 60mA during reception. It is housed in a 44-TQFN exposed pad package and functions within a temperature range of -40°C to 85°C.

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the received unit matches the specific 44-TQFN package configuration and operational voltage requirements. Ensure handling procedures comply with electrostatic discharge protection standards for sensitive RF components. Review current availability status as product lifecycle stages may affect supply continuity.

RF Transceiver ICS Selection Notes

Select this module when a compact SiP solution is required for 802.11b/g compliance. Consider the 18dBm output power and -96dBm sensitivity for link budget calculations. Evaluate the 3.3V supply constraint against system power architecture. Verify SPI interface compatibility with the host microcontroller. Assess thermal management needs given the -40°C to 85°C operating range.

RF Transceiver ICS Part Context

The HDG204 series represents H&D Wireless AB's approach to integrating complete WLAN functionality into a small footprint. This specific model targets applications where space constraints and power efficiency are critical. It consolidates RF front-end and baseband processing into a single SIP unit, simplifying PCB layout compared to discrete component solutions.

RF Transceiver ICS Replacement Considerations

No public confirmed substitute part numbers are available. Due to the proprietary nature of the SiP integration and specific RF tuning, direct pin-to-pin replacements from other manufacturers may not guarantee equivalent performance without extensive redesign.
