Evaluation Board Description

General Description

The TH71081 antenna board is designed to

optimally match the differential power amplifier

output to a loop antenna. The TH71081 board is

populated for ASK transmission.

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

850 MHz to 930 MHz

Adjustable equivalent radiated power (ERP)

range from -20 dBm to -6 dBm

! Adjustable current consumption from

6.2 mA to 12.5 mA

! ASK achieved by on/off keying of internal

power amplifier

! Differential output well-suited for loop antenna

! Conforms to EN 300 220 standard

! Wide power supply range from 2.2 V to 5.5 V

! High over-all frequency accuracy

! Very low standby current
