Frequency synthesisers survive satellite
use
The most fundamental benefit of UltraCMOS products for space applications is its ability to integrate RF, mixed signal analogue and digital on the same device.
Peregrine Semiconductor has released the UltraCMOS PE97022 and PE97042 phase locked loop (PLL) frequency synthesisers for satellite payload designs The 3.5GHz Integer-N PLLs boast a normalised phase noise of -216dBc/Hz, which is the lowest phase noise of any rad-hard PLL on the market today

CMOS antenna switch beats exotic alternatives
The PE4263 SP6T RF antenna switch is the latest innovation in the expanding RF product portfolio from Peregrine Semiconductor.
CMOS antenna switch is a first for dual-band GSM
The PE4261 is billed as the world's first flip-chip SP4T RF antenna switch for dual-band GSM handset applications.
Additionally, the two PLLs feature programmable counters, a phase comparator and a +10/11 Dual Modulus Prescaler, allowing for backward compatibility with previous generation PLLs.
The PE97042 offers direct or serial programming modes, while the PE97022 offers an additional parallel mode option.
Phase-locked loop (PLL) synthesisers for skew suppression, frequency synthesis for local oscillators, signal modulation and demodulation, clock recovery, jitter reduction, regeneration of signals and pulse synchronisation of signals from mass storage devices.
Phase noise has traditionally been a challenge for any satellite application.
The UltraCMOS silicon-on-sapphire based devices are fully space qualified and immune to single event latch-up (SEL).
A resistance to single event upset (SEU) of less than 10-9 errors per bit-day and tolerance to total dose radiation of up to 100krads (Si) make these devices suitable for the demanding rigors of space applications.
Further, because the PE97022 and PE97042 are manufactured on the UltraCMOS process, the devices use approximately 45mA to meet system-level requirements.
The most fundamental benefit of UltraCMOS products for space applications is its ability to integrate RF, mixed signal analogue and digital on the same device.
Both devices are offered in the 44-pin CQFJ package, while the PE97042 is also available in die form.
The PE97022 is a drop-in replacement for the PE9702, while upgrading from the PE9704 to the PE97042 requires only minimal design modification.
