Green UHF-TV Transmitters
By Mark Murphy, Marketing Director, RF Power, NXP Semiconductors

Fred Ortiz, President, dB Control

As digital television rolls out across the world replacing older analog systems, the pressure that manufacturers of broadcast equipment are under to deliver richer content is driving the need for higher efficiency transmitters that utilize the maximum power available and are as cost-effective as possible. At the same time TV network operators are being forced to look for ways to reduce the amount of electricity used to power their networks and reduce their operating costs.  The easiest way to achieve this is to improve the efficiency of the power amplifiers but it has to be achievable without any addition cost penalty. However this is not an easy task as UHF-TV transmitters have to be able to function over a very wide-band from 470 -860MHz.  At NXP we have come up with an innovative way to solve this challenge by developing the UWB Doherty for UHF where we have a 50% relative improvement in amplifier efficiency versus a classical class AB configuration. In addition, it has achieved this innovation without an increase in the bill of materials.

If you dig further down into the real challenges of the transmitter manufacturers it becomes clear they give most of their attention to high energy consumption and the complex cooling systems. An increase in the efficiency of the power amplifier in the UHF-TV transmitter can not only increase the efficiency of the transmitter but would also result in reduced size and cost of the cooling system. With the industry-first ultra wideband solution for Doherty architectures NXP is uniquely enabling manufacturers of these digital transmitters to enjoy the high efficiency gains that Doherty confers with greatly expanded bandwidth. This high efficiency solution uses NXP’s leading edge 50V LDMOS technology and supports the full UHF band without any compromise in power and cost. Over the next few months NXP will create UWB Doherty demonstrators based on the BLF884P and BLF88A.

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
