Richardson Electronics and Scintera Expand Breakthrough Linearization Technology to UHF Broadcast TV Power Amplifiers

The Two Companies Display New Solution at APMC 2010, in Yokohama, Japan

Tokyo, Japan - : Richardson Electronics, Ltd. announces that it has once again teamed with Scintera®, Inc., to bring the newly enhanced SC1887-03 Adaptive RF Power Amplifier Linearizer (RFPAL) to the UHF broadcast TV transmitter market. This fully adaptive, "RF-in, RF-out" amplifier pre-distortion solution operates directly at the carrier frequency, and requires only the addition of a few standard RF components to implement. The Scintera SC1887-03 RFPAL is a practical, cost-saving solution that satisfies today's digital broadcast TV needs for reduced amplifier distortion and increased power efficiency, across a broad range of digital broadcast television power levels. The RFPAL precisely compensates power amplifier non-linearities including AM/AM and AM/PM distortion, spectral regrowth, memory effects and other system level impairments. The new solution will be on display in Richardson Electronics' booth (D303) at the Asia Pacific Microwave Conference in Yokohama, Japan.

"Scintera's versatile amplifier pre-distortion technology helps RF designers to achieve the newest digital broadcast television performance specifications, without having to constrain the amplifier design to a power-backoff mode," says Chris Marshall, Vice President of Marketing and RF/Microwave Components for Richardson Electronics. "This field-proven, system-on-a-chip (SoC) approach can therefore both improve transmitter performance and reduce overall cost in all DVB (T/H/T2), CMMB, DTMB, ISDB-T and ATSC television applications."

Kris Rausch, Vice President of Sales and Marketing at Scintera, Inc., added "We are proud to team-up once again with Richardson Electronics to bring our SC1887-03 to market on a global basis. Over the past year, the Scintera/Richardson team has helped countless design engineers to improve performance and get to market quickly with advanced power amplifier designs in wireless cellular communication systems. Together, we are now extending the same benefits to the world's digital broadcast TV transmitter designers."

The SC1887-03 covers the UHF frequency range from 470 to 862 MHz and provides up to a 26 dB improvement in adjacent channel leakage rate (ACLR) performance. Its operating temperature range is -40⁰C to +75⁰C making it suitable for outdoor applications. The SC1887-03 is available in a 9x9 mm, 64-pin QFN package and is fully RoHS compliant
In addition to the SC1887-03 RFPAL itself, Richardson can also provide a simplified reference design for the product. Richardson Electronics also stocks the important SC1887-EVK500 evaluation kit, which serves two purposes:

1. It is used to test and evaluate the SC1887-03; and,

2. It can be used as well during the development process for design-integration.
Please visit the Scintera storefront on Richardson Electronics' website. Pricing starts in volume at $95 for 100 pieces for the SC1887A-03A00 and $1,100 for the SC1887-EVK500 kit.
