A Monolithic Alternative to Discrete, PIN-Diode
Limiters, the Next-Generation UltraCMOS® PE45361 Delivers Reliable and Repeatable Receiver
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.
