TAMPA, Fla. -- June 3, 2014

IMS 2014 – In Booth #515 Peregrine Semiconductor Corp. (NASDAQ: PSMI), founder
of RF SOI (silicon on insulator) and pioneer of advanced RF solutions,
announces the availability of UltraCMOS® PE45140 and PE45450 RF power
limiters. Peregrine’s power limiters represent the industry’s first turnkey,
monolithic solutions to provide an alternative to discrete, PIN-diode limiters
based on gallium arsenide (GaAs). Now shipping, these components offer
repeatable and reliable protection designed for test-and-measurement,
land-mobile-radio (LMR), wireless-infrastructure, military and radar systems.

“Peregrine is excited to deliver the industry’s first monolithic power
limiters – UltraCMOS PE45140 and PE45450 – today,” says Kinana Hussain, senior
marketing manager at Peregrine. “Because we were able to architect the entire
solution onto a single chip, Peregrine’s programmable power limiters offer
unique flexibility and unprecedented, robust RF protection to designers of
test-and-measurement equipment, LMRs, wireless-infrastructure devices and
military and radar systems.”

Peregrine designed the UltraCMOS PE45140 to accommodate the frequency ranges
needed in military, LMR and radar applications. Specifically, this power
limiter can protect RF front ends and low-noise amplifiers (LNAs) in LMRs;
tactical radio receivers from intentional jammers in military warfare; and
transceiver (TRX) modules in radiolocation, shipborne and air-traffic-control
(ATC) radar systems. Designed for higher frequency ranges, the PE45450 can
protect RF ports in test-and-measurement equipment and RF receivers in
wireless-infrastructure equipment.

Both power limiters feature:

  *High maximum power handling up to 50 W
  *Form factor as much as eight times smaller than PIN diode solutions
  *Greater than 40 dB linearity (IIP3) improvement over PIN diode solutions
  *Fast response-and-recovery time of less than one nanosecond
  *Adjustable limiting threshold starting as low as +22 dBm and reaching as
    high as +35 dBm
  *Superior ESD ratings as high as 8 kV HBM
  *Dual-mode operation (power-limiting mode and power-reflecting mode)

Peregrine’s programmable power limiters feature two operating modes: power
limiting and power reflecting. These modes can be selected through a low
current, analog voltage on the control pin (V[CTRL]). In the power-limiting
mode, the device is invisible to the load, and it features very low insertion
loss and high linearity. When the incoming RF-signal power exceeds the
limiting threshold set through the V[CTRL ]pin, the device limits the input RF
power. In the power-reflecting mode, the device reflects most of the incident
power back to the source. The power-reflecting mode also uses an external
power detector to sample the input RF power and toggle the V[CTRL ]pin from
power-limiting to power-reflecting mode for maximum protection. These power
limiters also protect RF ports in unpowered or unbiased conditions.

Features, Packaging, Pricing & Availability

Peregrine’s PE45140 and PE45450 feature a wide frequency range from 20 MHz to
2 GHz, and 9 KHz to 6 GHz respectively. Both power limiters feature fast
response-and-recovery time of less than 1 nanosecond and protect systems from
RF power spikes and surges in harsh environments. The power limiters’ high ESD
ratings of up to 8 KV (HBM) protect RF ports from ESD events and enable the
devices to operate as ESD clamps. Because PE45140 and PE45450 do not need
additional external components, such as DC blocking capacitors, RF choke
inductors and bias resistors, these power limiters reduce the overall
power-limiting-function footprint and BOM costs. Available now in a compact
12-lead 3x3mm QFN package, PE45140 costs $6.90 each in 10K quantity orders and
PE45450 costs $7.80 each in 10K quantity orders. Evaluation kit boards are
$130 each.
