s Power down

DESCRIPTION

The TSH690 is a wide band RF amplifier, de-

signed in advanced bipolar process. At 450 MHz,

it features 28dB gain and +13.5dBm (20 mW) out-

put power at 3V. At 900 MHz, it features 23 dB

gain and +15.5 dBm (35 mW) output power at 3V.

The pin 8 allows a bias current adjust, setting the

RF output level and the amplifier behaviour. It al-

lows using the TSH690 from the linear A-class

trough the AB-class to power-down mode.

The TSH690 is suited to drive power amplifiers in

cellular phones (GSM, TDMA) for which the

’turn-on time’ is controlled by a voltage ramp.

The more than 20 mW output power makes the

TSH690 dedicated as output stage for 433MHz

and 868 MHz ISM transmitters.

APPLICATIONS

s 433 MHz and 868 MHz ISM transmitters

s Telemetering systems

s Remote controls

s Cordless Telephones

s Driver for cellular phones

s Wide band applications
