A Monolithic Alternative to Discrete, PIN-Diode Limiters, the Next-Generation UltraCMOS® PE45361
Delivers Reliable and Repeatable Receiver Protection
London – European Microwave Week – Oct. 4, 2016 – Peregrine Semiconductor
Corp., founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, announces the
UltraCMOS® PE45361, a monolithic 100-watt power limiter. The next generation in Peregrine's
power limiter product family, the PE45361 builds on the success of the award-winning 50-watt UltraCMOS
power limiters and adds higher pulsed power handling, a lower limiting threshold and positive threshold
control. UltraCMOS power limiters provide a monolithic alternative to discrete, PIN-diode limiters based
on gallium-arsenide (GaAs) technology and protect devices against excessive RF power, intentional jamming
and ESD events. The PE45361 delivers reliable and repeatable power protection to sensitive low-noise
receivers for test-and-measurement equipment and wireless-infrastructure transceivers.
- Monolithic drop-in solution with no external bias components
- Adjustable low power limiting threshold from +5 dBm to +13 dBm
- High maximum power handling of 50 dBm, 100W
- Positive threshold control of +0V to +0.3V
- Fast response time of 1 ns
- Packaging – 12-lead 3 × 3 × 0.5 mm QFN
"Peregrine's monolithic power limiters offer our customers a novel and robust approach to excessive
RF power protection," says Kinana Hussain, director of marketing at Peregrine Semiconductor. "The introduction
of the PE45361 builds upon the key RF performance and bill of materials (BOM) cost advantages of our
UltraCMOS limiters, while providing 100W power handling and low limiting threshold to protect sensitive
low-noise amplifiers (LNAs)."
Compared to PIN diodes, UltraCMOS power limiters provide a 10–100x improvement in response-and-recovery
time, deliver 10–40 dB linearity (IIP3) improvement and offer a 20x improvement in ESD protection. In
addition, UltraCMOS power limiters are 8x smaller than the board space required by PIN-diode solutions.
Finally, the limiting threshold can be adjusted through a low current voltage control pin (VCTRL), eliminating
the need for external components such as DC blocking capacitors, RF choke inductors and bias resistors.
Like other UltraCMOS power limiters, the PE45361 features two operating modes — power limiting and
power reflecting — to maximize performance and flexibility. These modes can be selected through the
programmable VCTRL pin. In power-limiting mode, the device is invisible to the load. When the incoming
RF signal power exceeds the limiting threshold set through the VCTRLpin, the device limits the input
RF power. Power-reflecting mode is used in more extreme conditions, and the device reflects most of
the incident power back to the source.
Features, Packaging, Price and Availability
Covering a wide frequency range from 10 MHz to 6 GHz, the PE45361 power limiter provides exceptional
power protection for high performance, power-limiting applications. It features a high pulsed power
handling up to 50 dBm and 100 watts, an adjustable limiting threshold from 5 dBm to 13 dBm and a positive
threshold control from 0 volts to 0.3 volts. The PE45361 delivers low insertion loss of 0.95 dB at 6
GHz and high return loss of 15 dB at 6 GHz. With a fast response time of 1 nanosecond and a speedy recovery
time of 20 nanoseconds, the PE45361 exhibits high linearity of 37 dBm IIP3 and excellent ESD protection
of 3 kV HBM. Samples and evaluation kits are available now. Offered in a compact 12-lead 3 x 3 mm QFN
package, the PE45361 is $4.80 each for 10k-quantity orders.
