40MHz to 1GHz AMPLIFIER
DESCRIPTION
TSH690 is a wide band RF amplifier, consisted of
2 stages, designed in advanced bipolar process
featuring 28dB gain and +13.5dBm output power
at 450MHz under 3V. The pin 8 allows an external
bias current adjust to tune the output power and
also to set the amplifier in power-down mode. This
powerful amplifier is dedicated to equip secured RF
data transmitters as antenna drivers in ISM band
(reliable RF meter-reading systems, secured Re-
mote Controls, Cordless Telephones, ...)
