New-Generation MOSMIC™ RF Transistors From Vishay, Specified for a Supply-Voltage Range of 3 V to 7 V, Provide Space Savings for Digital and Analog TV Tuners
MALVERN, PENNSYLVANIA — March 21, 2003 — 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. (NYSE: VSH).
The new MOS Transistor (MOSMIC™) 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 AGC (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.
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.
