TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA4303F
Down Converter for BS/CS Tuner IC
Description
The TA4303F is a monolithic IC to down-convert the L-band
(900~2150 MHz) signal for the satellite tuners. It's integrated
circuits that perform the mixer/oscillator function. They have
double-balanced mixer, local oscillator, IF amplifier, OSC buffer
amplifier and prescaler buffer amplifier circuits.
Features
z Single chip full band solution, compatible with digital and
analog transmissions.
z Single 5 V power supply operation
z Full band constant convertion Gain and Noise Figure
z Local oscillator output circuit for PLL
z Low Phase Noise local oscillator
Weight: 0.17 g (typ.)

Note:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
