General Description
The LND TRM33 is a low power Amplitude Shift Keying (ASK) transmitter designed to operate at transmit frequencies between 300 and 500MHz. It is comprised of a frequency synthesizer and modulator, which accepts a simple CMOS digital data input and generates an ASK modulated output. Output power can be adjusted to a maximum of 2dBm. The LND TRM33 has been optimized for use in battery-powered applications with low current consumption in both transmit and standby modes.

FEATUREs
• Low current consumption in transmit mode
• Low standby current (typically a few nA)
• Conforms to requirements of ETSI-300-220, PT1340 and FCC Part 15
• Easy to use with low external component count and cost
• No discrete external inductors required
• Adjustable output power level

APPLICATIONs
• Wireless office and home security systems
• Automotive remote locking/starting
• Consumer remote control units
• Radio data transmission
• Low power telemetry
