Overview
The HFA3624IA1K-INT is a monolithic bipolar RF/Microwave up/down converter designed for the 2.4GHz to 2.5GHz frequency range, manufactured using the Intersil UHF1X process. It operates with an intermediate frequency (IF) range of 10MHz to 400MHz and supports single supply battery operation from 2.7V to 5.5V. The device integrates a low noise amplifier and down-conversion mixer in the receive section, alongside an up-conversion mixer with power preamp in the transmit section. It features independent receive/transmit power enable mode for time division multiplexed systems and requires low local oscillator drive levels.
Feature Summary
- Complete integrated receive and transmit front end solution
- Energy-saving power enable control ensuring isolation between circuits
- Low local oscillator drive level requirement
- Small outline 28 lead SSOP package design
Applications
- Systems targeting IEEE 802.11 Standard
- PCMCIA Wireless Transceiver
- Wireless Local Area Network Modems
- TDMA Packet Protocol Radios
- Portable Battery Powered Equipment
Procurement Notes
Verify that the specific suffix '1K-INT' corresponds to the standard HFA3624IA component specifications, as datasheets typically list HFA3624IA. Confirm the temperature range is -40°C to 85°C. Ensure the package is identified as 28-lead SSOP. Check for RoHS compliance status if required by your manufacturing standards. Validate the manufacturer origin as Intersil or Renesas Electronics Corporation.
Selection Notes
Select this component for Direct Sequence Spread Spectrum (DSSS) RF modem applications within the 2.4GHz ISM band. It is suitable for designs requiring a highly integrated five-chip PRISM chipset solution. Consider its suitability for PCMCIA card form factors due to the small package size. Evaluate its compatibility with single-supply battery-powered portable equipment constraints.
