TA4303F
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
Single chip full band solution, compatible with digital and analog transmissions. Single 5 V power supply operation Full band constant convertion Gain and Noise Figure Local oscillator output circuit for PLL Low Phase Noise local oscillator Weight: 0.17 g (typ.)

Absolute Maximum Ratings (Ta = 25C)
Characteristic Supply voltage Total power dissipation Operating temperature Storage temperature Symbol VCC PD (Note 1) Topr Tstg Rating 6 1100 -20~85 -45~150 Unit V mW C C
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).
