NEW-GENERATION MOSMIC™ RF FRANSISTORS FROM VISHAY
21 March 2003 - Vishay Electronic

A new generation of RF transistors optimized to provide excellent dynamic performance and significant space savings in TVs, VCRs, set-top boxes, and satellite systems has been launched by Vishay Intertechnology, Inc. The new MOS Transistor devices released today include two single MOSMICs, the S505TY and S506TY, respectively optimized for UHF and VHF amplification, and a dual MOSMIC with both UHF- and VHF-optimized amplifiers, the TSDF02830Y. All three MOSMICs will serve as low-noise, gain-controlled input stages in digital and analog TV tuners.

The new MOS Transistor devices released today include two single MOSMICs, the S505TY and S506TY, respectively optimized for UHF and VHF amplification, and a dual MOSMIC with both UHF- and VHF-optimized amplifiers, the TSDF02830Y. All three MOSMICs will serve as low-noise, gain-controlled input stages in digital and analog TV tuners.

The new MOSMIC devices from Vishay Semiconductors are specified for a supply-voltage range of 3 V to 7 V and feature a high, soft-slope automatic gain control range to minimize noise. The S505TY, S506TY, and TSDF02830Y also provide easy Gate-1 switch-off with PNP switching transistors inside the PLL. Additional integrated features include gate-protection diodes and a partly internal self-biasing network.

Typical forward transadmittance is 31 mS for the UHF-optimized S505TY and the UHF amplifier of the dual TSDF02830Y. Input capacitance is 1.9 pF, with a typical noise figure of 1.3 dB at 800 MHz.

For the VHF-optimized S506TY and the VHF amplifier of the dual TSDF02830Y, typical forward transadmittance is 28 mS, with input capacitance of 2.5 pF and typical noise of 1.5 dB at 800 MHz.

All three devices offer superior cross modulation at gain reduction. At typical frequencies of fwanted= 50 MHz and funwanted= 60 MHz, k = 1% of cross modulation at 40 dB AGC (automatic gain control) is achieved for input levels up to min. 100 dBµV in the UHF-optimized MOSMIC amplifiers and up to min. 105 dBµV in the VHF-optimized amplifiers

Packaging options for the S505TY and S506TY are the compact, surface-mount SOT143, SOT143R, or SOT343R. The TSDF02830Y is available in the SOT363, SOT363R, and SOT363L SMD packages, which share a common outline but feature different internal pin configurations to accommodate a wider variety of applications.

Samples and production quantities of the new MOSMICs are available now, with lead times of 8 to 10 weeks for larger orders.
