Philips Semiconductors launches next generation MOSFET family for TV/VCR tuners
Philips Semiconductors, a division of Royal Philips Electronics, has launched its new range of N-channel dual-gate MOSFETs for TV and VCR tuners. Designed to cut noise and cross modulation in such tuners, the BF1201 / BF1202 / BF1203 and BF1204 offer significant performance improvements over comparable products on the market. The range incorporates the next generation of 2-in-1 products that are worthy offerings from the leader in this field.
The new range includes the BF1201 and BF1202 N-channel dual-gate PoLo MOSFETs for VHF and UHF applications with 3-9 supply voltage, such as digital and analogue television tuners and professional communications equipment. The BF1201 is optimized for cross-modulation and the BF1202 is optimized for noise.
The products are enhancement type N-channel field-effect transistors with source and substrate interconnected. Integrated diodes between gates and source protect against excessive input voltage surges. Both feature high forward transfer admittance to input capacitance ratio partly self-biasing circuits to ensure good cross modulation performance during AGC and good DC stabilization.
Jos Zeelen, International Product Marketing Manager for Tuning Products at Philips Semiconductors said: "These innovative products offer a very significant improvement on competitor offerings which do a similar job. They provide a good demonstration of how Philips Semiconductors' commitment to producing innovative products is helping to maintain its position as the world leader in MOSFETs."
Building on the success of the BF1201 and BF1202 family, which offers various pinning and packaging options, Philips Semiconductors has developed two other companion products in response to specific customer demands - the BF1203 and the BF1204. Although designed to meet the needs of two major customers who are global market leaders in their fields, the BF1203 and BF1204 are not customized and are now available for all customers.
The BF1203 is a combination of two different dual gate MOSFET amplifiers with shared source and gate 2 leads in a single package. The BF1204 is a combination of two equal dual gate MOSFET amplifiers with shared source and gate 2 leads in one package. Both products feature superior cross-modulation performance during AGC and high forward transfer admittance to capacitance ratio. The source and substrates are interconnected and the internal bias circuits enable DC stabilization as well as the excellent cross-modulation performance. Integrated diodes between the gates and source protect against excessive input voltage surges. Both are available in SOT363 micro-miniature plastic packages.
As well as offering additional performance benefits, the 2-in-1 packages offer significant cost savings, in the cost per piece compared with using two products, but also in logistics and placement costs. The 2-in-1 products also take up less space on the PCB than using two products to do the same job, which supports the drive towards miniaturization as well as enhancing tuner design.
All the products in the range are in full production and samples are available immediately.
