Richardson RFPD Announces Design-In Support and Immediate Availability of Breakthrough LDMOS RF Power
Transistors for UHF Broadcast
- Freescale™ Semiconductor’s New MRFE6VP8600H and MRFE6VP8600HS
September
20, 2011 – LaFox, Illinois: Richardson RFPD, Inc. today announces the availability of two breakthrough 50V LDMOS
RF power transistors which set new standards for ruggedness in the UHF broadcast industry. The
MRFE6VP8600H and
MRFE6VP8600HS are push-pull power transistors that provide enhanced efficiency and operate over the 470 – 860
MHz frequency band. These devices are capable of transmitting highly-linear, 125W average DVB-T output power, with
a peak envelope power output capability of over 600W. Moreover, these devices are fully capable of withstanding a
nearly 100% mismatched load, specified as greater than 65:1 VSWR at all phase angles, with no damage to the
transistor. Ultimately, the
MRFE6VP8600H and
MRFE6VP8600HS provide a unique combination of linear power amplification, high efficiency and enhanced
ruggedness never before seen in the UHF broadcast industry.
Key features: · Capable
of 18.8 – 20.0 dB gain · P1dB > 600 watts · Average output power rated at 125 watts (DVB-T 8k OFDM)
· Rugged devices withstand a 65:1 VSWR load mismatch
with no damage over all phase angles Integrated enhanced ESD protection · High
power-added-efficiency, typically 30 percent (up to 45 percent in Doherty configuration) · Extended
operating range characterized from 20V to 50V for use with drain modulation schemes (ex. envelope
tracking) · Extended negative gate-source voltage range (-6V to +10V) · Two air cavity
ceramic package options: choose bolt- down or solder-attach · RoHS compliant
Design advantages: · Reduction in the total number of transistors and combiner stages needed
for a given output power level allows for simplified overall UHF transmitter design and improved
reliability. · Broadband internal input impedance matching means these devices are easier to implement.
· Extended negative gate-source voltage range provides improved Class C operation (such as when used in
the peaking stage of a Doherty amplifier). · High-efficiency means less current is consumed, and as a result
less power is wasted as heat. A UHF transmitter designed with these devices can use 15% less energy than
previous generation transistors. · Enhanced ruggedness makes it possible to use more simplified
transmitter protection circuitry. The
MRFE6VP8600H and
MRFE6VP8600HS are in stock and ready for shipment. Full design support and product documentation is readily
available. To find more information, or to purchase these products today on the Richardson RFPD website, please

Local Sales Support.
In addition, Richardson RFPD and Freescale Semiconductor will assist all
interested RF engineers by providing specific design recommendations for these rugged LDMOS transistors during an
upcoming free webinar. This webinar will be hosted by Microwave Journal on Thursday, September 29, 2011, beginning
at 8am PT (11am ET / 3pm UTC).
Registration is available through Microwave
Journal’s Events site.
