315/433MHz Transmitter

Evaluation Board Description

General Description

The TH7107 antenna board is designed to

optimally match the differential power amplifier

output to a loop antenna. The TH7107 can be

populated either for FSK, ASK or FM

transmission. The default population is for FSK or

ASK transmission. Adding a varactor diode can

easily be done in order to modify the circuit for

analog FM. The evaluation board contains a

differential-drive loop antenna printed on the PCB

(Printed Circuit Board). The size of the loop

antenna is matched to the resonant frequency.

Board layout data in Gerber format is available on request.

Features

! Fully integrated, PLL-stabilized VCO

! Flexible frequency range from

310 MHz to 440 MHz

! Adjustable equivalent radiated power (ERP)

range from -25 dBm to -10 dBm

! Adjustable current consumption from

4.8 mA to 11.5 mA

! FSK through crystal pulling allows modulation

from DC to 20 kbit/s

! Frequency deviation and center frequency

independently adjustable

! High deviation possible for wideband data

transmission

! Differential output well-suited for loop antenna

! External clock available for µC drive,

down to 1.9 V supply

! ASK achieved by on/off keying of internal

power amplifier

! FM possible with external varactor

! Wide power supply range from 2.2 V to 5.5 V

! High over-all frequency accuracy

! Very low standby current

! ”Clock only” mode

! Conforms to EN 300 220 standard
