Teledyne e2v HiRel announced the availability of a low phase noise 13.9 GHz, delta-sigma modulated fractional-N connectorized frequency synthesizer module for low earth orbit (LEO) space and other demanding applications.

The TDFFS014 is a ready-to-use package equipped with SMA connectors, allowing engineers to quickly prototype designs without the need for evaluation boards.

The TDFFS014 is a fractional-N frequency synthesizer module with 12.5-13.9 GHz and 6.25-6.95 GHz outputs. The module is optimized for commercial space and high reliability applications and has superior phase noise performance of -102 dBc/Hz (13 GHz at 100 kHz offset, typical).

It features a radiation tolerant Teledyne PE97640 Frac-N PLL, active 5th order loop filter, GaAs InGaP HBT MMIC VCO with integrated divide-by-4 and divide-by-2 pre-scalers, and voltage regulators for low phase noise operation.

Reference oscillator input and RF outputs are SMA connectors. Power supply inputs, 3-wire serial interface, and ground are made through a female, 15-pin Micro-D connector. It is available with seam welded or bolt-on housing lid.

“The new TDFFS014 offers 10 mW output power simultaneously on its main RF output and RF/2 output,” said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel. “Designers can drive common types of mixer without resorting to an intermediate low noise amplifier (LNA), further simplifying system design.”

Samples are available for ordering, from Teledyne e2v HiRel or an authorized distributor. They are shipped from DoD Trusted Facility in Milpitas, California.

Teledyne is doing demonstration of the Frequency Synthesizer module at Booth 3068 at the IMS Show in Denver.
Teledyne e2v HiRel also announced the availability of a rad-tolerant 30 GHz, Single Pole Double Throw (SPDT) reflective RF switch, model TDSW030A2T, that is ideal for use in demanding high reliability, space and defense applications and is now available with qualified material off-the-shelf.

This new RF switch, developed on 0.15 μm InGaAs pHEMT technology, will be available as die and is qualified per MIL-PRF-38534 Class K equivalency for space applications.

The TDSW030A2T switch delivers low insertion loss, high isolation, fast switching times, and high linearity across a wide frequency band from dc to 30 GHz and attains an input power 1 dB compression of 25 dBm (typical). Class K equivalent element evaluation is performed per wafer.

“This new product is the first 30 GHz switch qualified as TID radiation tolerant to 100 krad (Si) on the market,” said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel.
