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, ...)
