power amplifier up to 40 kbit/s
! Wide power supply range from 1.95 V to 5.5 V
! Very low standby current
! On-chip low voltage detector
! High over-all frequency accuracy
! FSK deviation and center frequency independ-
ently adjustable
! Adjustable output power range from
-12 dBm to +10 dBm (at connector board)
! Adjustable effective radiated power (ERP) range
from -24 dBm to -2 dBm (at antenna board)
! Adjustable current consumption from
3.4 mA to 10.6 mA
! Conforms to EN 300 220 and similar standards

Evaluation Board Example
General Description
The TH72015 evaluation board is designed to demonstrate the performance of the transmitter IC with an
on-board loop antenna. This board allows the user to setup an RF transmitter very easily. Alternatively a
50 Ohm connector board can be requested.
