T5753C-6AQJ-66

RF Transmitter Overview

The T5753C-6AQJ-66 is a UHF ASK/FSK RF transmitter IC manufactured by Microchip Technology. It operates within the 310 MHz to 350 MHz frequency range, supporting data rates up to 32 kBaud. The device delivers an output power of 8 dBm and utilizes a surface-mount 8-TSSOP package. It functions with a supply voltage range of 2.5 V to 3.3 V and supports both PCB and surface mount antenna configurations for wireless signal transmission.

RF Transmitter Feature Summary

• Supports Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK) modulation schemes
• Integrated UHF transmitter functionality for short-range wireless communication
• Compatible with direct PCB trace or external surface mount antenna implementations

RF Transmitter Applications

• Remote keyless entry systems
• Wireless sensor network transmitters
• Industrial telemetry data links

RF Transmitter Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified partners. Request official datasheets and test reports to confirm operational specifications against the 310-350 MHz band requirements. Ensure packaging integrity matches the 8-TSSOP form factor before integration into production lines.

RF Transmitter Selection Notes

Select this component when designing circuits requiring reliable UHF transmission in the 310-350 MHz ISM band. Consider the 8 dBm output power capability and 32 kBaud data rate limits relative to system latency needs. Evaluate the 2.5 V to 3.3 V operating voltage constraints against available power rails in the target application environment.

RF Transmitter Part Context

This part belongs to the Microchip T57xx series of low-power RF transmitters. These components are designed for simple, cost-effective wireless control applications. The T5753C variant specifically targets the lower UHF frequencies, distinguishing it from higher-frequency counterparts like the T5754 series which operate at 433 MHz.

RF Transmitter Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative models such as the T5750 or T5754 series only if frequency bands and modulation types align with specific design modifications.
