MICRF033BM

RF Receivers Overview

The MICRF033BM is a QwikRadio 900 MHz UHF receiver manufactured by Micrel, now part of Microchip Technology. It operates within the 800 MHz to 1 GHz frequency range and supports On-Off Keying (OOK) modulation with data rates up to 20 kbps. The device features a sensitivity of -95 dBm and is designed for surface-mount applications in an 8-SOIC package. It functions as a specialty consumer circuit with one functional unit, operating between -40 °C and 105 °C.

RF Receivers Procurement Notes

Verify the manufacturer designation carefully, as sources list both Micrel and Rochester Electronics. Confirm the specific suffix or revision level against the official datasheet to ensure compatibility with your design requirements. Check for lead-free status if required by your assembly process specifications.

RF Receivers Selection Notes

Select this component when a low-cost, fixed-frequency UHF receiver is needed for basic remote control or telemetry tasks. Ensure the application environment stays within the specified temperature range. Verify that the 20 kbps data rate meets the system's throughput requirements before finalizing the design.

RF Receivers Part Context

This receiver belongs to the QwikRadio family, which targets simple wireless control applications. It is often used in legacy or cost-sensitive designs where complex protocol stacks are unnecessary. The SOIC-8 package facilitates easy PCB layout for small form-factor devices.
