Passive and Control Components

Programmable Attenuator


RS 216The M-DVAN-6018-60DD-SK is a programmable attenuator that incorporates a new linearization circuit to enable fast and accurate attenuation switching. The new design focuses on quick settling and stable operation over temperature extremes. Switching between any attenuation level is typically settled within 1 dB in about 400 ns. This attenuator offers temperature stability of ±1 dB over -10° to 85°C. The M-DVAN-6018-60DD-SK uses a hermetic MIL-C-28747 14 pin connector. Size: 1.34” x 1.34” x 0.5”.

8 to 18 GHz Multiplexer

RS 218For wideband receiver applications, the 8 to 18 GHz spectrum is divided into medium-size slices (2 GHz) prior to the amplification stage. The role of the multiplexer is to pass the spectrum with flat insertion loss (1.25 dB) and provide adequate isolation of 70 dB between the channels, which directly affects the dynamic range of the signal detection. At cross-over regions, the requirement is to have overlapping channels, leaving the ambiguity of detection to finer filtration schemes further down the chain. Spectral overlapping regions can be realized using a power divider and isolators splitting of RF signals into equal paths. The SS-00159 is K&L Microwave’s solution for passband flatness and tight isolation, achieved using degree 10 cavity TEM combline filters, with resonators machined directly into the housing. This reduces the number of parts and provides greater control over RF leakages. The unit measures 4” x 3” x 0.5” with SMA connectors located on one side.

Clock Generators

This pair of clock-generation and distribution ICs offers a great combination of device integration, low-noise, low-jitter performance and signal output flexibility. The AD9520 and AD9522 include a 512-byte embedded EEPROM memory block, affording system engineers a programmable clock solution that can serve as both the source and system clock. By programming their own specific set of output conditions using the on-chip memory, designers can easily configure the AD9520/2 as the source clock to ensure initial processing functions are synchronized when the system is powered on or reset. Competing clock ICs require a separate source clock, which must be independently matched to the system processor or microcontroller in order to program the system clock chip, adding component count, cost and complexity to network line cards, wireless and broadband infrastructure, medical imaging, and data converter clocking designs.

The step size in the 300 MHz operating bandwidth is 1 Hz with maximum phase noise of -105 dBc/Hz at 1 kHz, -120 dBc/Hz at 10 kHz, -120 dBc/Hz at 100 kHz, and -120 dBc/Hz at 1 MHz offset. Non-harmonic spurious suppression is -60 dB typical with RF output power of +10 dBm over the specified operating band. Additional features include support for locking with external GPS 1 PPS source for long-term stability and manual field adjustable frequency tuning. The KHPS500530 supports RS-232, parallel, and SPI programming interfaces and with a +12 VDC supply at 1A maximum current in steady state.

Transmission-line Components

Solderless N Connector

RS 258Part number RFN-1006-I-WB features white bronze plating for a non-tarnish finish with enhanced electrical performance. The plating is ferrous metal free, which reduces inter-modulation interference. A ridged back end provides better sealing for the heat shrink boot included with the connector. A combination hex/knurl coupling nut allows for wrench or finger mating. The connector may be attached to multiple brands of high performance cables including Times LMR®-400, Andrew CNT®-400, CommScope WBC®-400 and Belden®RF-400. The connector is assembled with industry standard crimp tools with 0.429 inch and 0.118 inch hex dies.

uflex Cables

RS 259The company has developed PMTL uflex cables™, a new patent pending, transmission line technology, for high speed interconnect and packaging of devices and systems. The initial PMTL uflex cables provide stable phase, group delay, and impedance, with low insertion loss and extremely low cross talk, under bending, twisting, and mechanical distress, from DC to 50 GHz, and scalable to work to 220 GHz and beyond. RFCONNEXT initially will provide a family of products, such as single and differential impedance flex/rigid jumper/connectors, wafer and PCB probes, test fixtures and sockets, and technical service targeting the signal integrity, and testing connectivity market, across the spectrum. The beautify of the PMTL technology is that it can be implemented on current low cost materials, rigid or flex, and uses the existing photolithographic technology for PCB or CMOS processes, thus allowing to increase density and achieving high speed with digital pulses of fractional pSec rise times.

High Performance Cable Assemblies

RS 260San-tron Inc. has announced the release of a new high performance connector to address the problem of signal transmission and fragility of solder joints in hand-formable cable assemblies. This new eSMA connector features a new extended ferrule and enhanced performance from an innovative internal design. This connector also features: failure-proof coupling nuts; EZ style, solder free, captivated center contacts; and a solder damming positive cable stop. They come standard with gold plated bodies and gold plated center contacts. They are also weatherproof and provide 50 ohm constant impedance.
