 New VCO
The CRO2781A-LF in S-band operates at 2780 MHz with a tuning voltage range of 0.5 to 4.5 Vdc. It features a typical phase noise of -115 dBc/Hz @ 10 KHz offset and a typical tuning sensitivity of 9 MHz/V. Its industry standard MINI-16 package is just 0.5 x 0.5 x 0.22".
 Wideband PA Module
A new wideband power amplifier module for use in microwave radio, VSAT, military & space, fiber optic and broadband test equipment applications from 100 MHz to 20 GHz has been introduced. The HMC-C057 is a GaAs pHEMT MMIC PA in a miniature hermetic module.
 Coaxial to Waveguide Adapters
Coaxial to Waveguide Adapters are offered in a variety of configurations. Option A, broadband adapters, have excellent electrical specs that are maintained over the entire adapter bandwidth. Option B offers enhanced performance over a specific band of the unit’s bandwidth.
 Digital Communication Analyzer
The latest addition to the PXIT product family, the PXIT 10G Digital Communication Analyzer (DCA) with Passive Optical Network (PON) filter rate options and smart post processing for the PXIT N2100B DCA, helps optical transceiver test vendors reduce their cost of test.
 LED Drivers
This new family of LED driver ICs significantly reduces the number and size of external components required by drive circuits. Operating at switching frequencies up to 600 kHz, AP880X Series step-down, DC-DC converters require only four smaller and lower cost inductors and/or capacitors.
 RF Interface DAS Panel
Created to control the output power from PAs, the 15C2NB is designed to combine and attenuate RF signals in steps of 1 dB up to 70 dB of maximum attenuation. With the operating frequency covering 800 MHz to 3 GHz, this design is ready for field deployment for GSM, PCS, WiMAX and LTE network architectures.
 Phase-Locked Crystal Oscillator
The PLXO-50 Phase-Locked Crystal Oscillator is used as the frequency reference in a surveillance RADAR application. The PLXO, which operates at 50 MHz, maximizes system performance with its exceptional phase noise (<-150 dBc/Hz @ 10 KHz) and other features.
 Directional Antenna
A wide angle 2.4 GHz antenna, model HG2405P-135, is designed for compact installations and is ideal for Wi-Fi, PCS, DCS, and custom applications. It gives the system designer wide angle coverage of an area without multiple antennas or larger footprint antennas.
 Band Reject Filters - Tunable
Band stop and cavity filters that can be re-adjusted by the customer to new center frequencies are now available. These filters are tunable over a +/-7.5% center frequency range with minimal change in bandwidth. Operating temperature range is -55 to +85ºC.
 Fast Rise/Fall Time Logic
Four new logic devices which are optimized for systems requiring fast rise/fall times, low jitter, and low DC power consumption have been released. They provide operating clock and data rates of 13 GHz/13 Gbps, and are ideal for deployment in ATE, broadband T&M equipment, frequency synthesis and radar signal processing systems.
 Ultra Low Phase Noise VCO
Model CRO1220A-LF in L-band operates at 1220 MHz with a tuning voltage range of 0 to 5 Vdc. This VCO features a typical phase noise of -118 dBc/Hz @ 10 KHz offset and a typical tuning sensitivity of 2 MHz/V. It is well suited for satellite communication and microwave radio applications.
 Design Verification Test Systems
The GS-9000 Assisted GPS (A-GPS) Design Verification Test systems were designed around the 8960 wireless communications test set’s new A-GPS assistance data messaging test capabilities. The capabilities support A-GPS validation, Total Isotropic Sensitivity testing and A-GPS pre-conformance testing for mobile devices.

 This new high performance AWS Diplexer is ideal for applications that require a high level of TX-RX isolation. Featuring a 45 dB minimum TX-RX isolation, TX power rated at 3W CW, and low insertion loss, it has a temperature range of -20 to +85ºC and a maximum VSWR of 1.5:1. This compact mechanical packaging features SMA connectors on all ports, is available in UMTS and DCS, and can accommodate most other communication bands, including UWB, LTE and PCS bands.
Trilithic
Utilizing the “QC” interface, a wide range of connector types and loads can be chosen without ordering a custom circulator. Typical high power choices include N, HN, SC and EIA rigid line connectors. The circulator is operable over a 10% minimum bandwidth between 500 and 1600 MHz at power levels up to 50 kW peak and 1 kW average. Typical specs for the CT-1800-S Series are 20 dB min. isolation, 0.3 dB loss and 1.25 VSWR over 0 to 65ºC.
UTE Microwave
The 2500B series Microwave Signal Generators cover 100 kHz to 50 GHz, with extremely low phase noise; high rejection of harmonics, sub-harmonics and spurious; high output power level; and all with the fast frequency switching the company is known for. Six models are available, covering 2.5, 8, 20, 26.5, 40 and 50 GHz. The 50 GHz model is the flagship of the product line, offering a combination of fast switching speed and low phase noise not previously available.

Product Digest
Something that many take for granted - and without which some of my friends and relatives would be wandering the countryside - is in danger, the GPS satellite network. I’d heard a short news item about this on the radio, so when I got home, I Googled it and found a great article in The Pueblo Chieftain (Southern Colorado), “Backlog in GPS satellites may someday crimp use of navigational devices.”
By Joseph Hajduk, CEO, dB Control
If you’re like most RF and microwave engineers, it’s been a long time since anyone brought up the word “tube,” except for maybe tube socks. For those of us old enough to remember, tubes ushered in “the dawn of radio” and were the guts of the first TVs.
Actually, there are still quite a few engineers designing amplifiers and transmitters based on traveling wave tubes (TWTs) and other vacuum electronic devices (VEDs) such as klystrons and crossed-field amplifiers. These allegedly archaic devices remain the sole purveyors of “real” RF power. By that I mean kilowatts or megawatts – enough to power the brawniest broadcast transmitters, radar systems, and a wide assortment of defense systems such as electronic warfare or electronic countermeasures suites. In fact, it’s safe to say that every EW or ECM system now in service, and most of those on the drawing board, use or are being designed around amplifiers based on tubes. And tubes are also used to power the transponders in communication satellites.
