Miniature High Performance OCXO: NV79A Series

Miniature High Performance OCXO: NV79A Series

The NV79A is an ovenized crystal oscillator (OCXO) with low phase noise options and excellent frequency vs. temperature stability. 3.3Vdc and 5Vdc supply voltages are available, and the oscillator is available in frequencies from 10MHz to 50MHz.

High Performance Clock Oscillators: LV7 Series

High Performance Clock Oscillators: LV7 Series

The LV7 series of high performance clock oscillators are ideal for communications systems where low jitter is mandated by chipset suppliers and system level performance demands. The series is comprised of several different models with variations in frequency stability, operating temperature, and supply voltage. It collectively covers the 40 to 200 MHz frequency range.

Impedance Transformers

Impedance Transformers

ETL Systems presents a series of passive L-band transformers between 50Ω to 75Ω impedance that are available in DC & 10 MHz pass on both ports, DC & 10 MHz block on both ports, and DC block and 10 MHz pass on both ports. Standard packaging is available with all models, and a tubular package style is available for models with DC & 10 MHz pass on all ports. Components are available with 50Ω SMA, N-type, BNC and 75Ω BNC or F-type RF connector types. Applications for these transformers include telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks.

Space-Qualified SAW Devices

Phonon has been producing an extensive legacy of space-qualified SAW devices since 1987. All products are built to each customer’s individual requirements. Products can be built for either commercial or military space applications. Our space-qualified products are all built to MIL-PRF-38534 Class K reliability.

Safe-Guard RF Switch

Safe-Guard RF Switch

This RF switch has been designed to attenuate the RF transmit signals up to 12dB or to a reduced power level of 6.3% of the original power. It’s particularly well suited for the oil and gas industry.

Four-Bit Digital Attenuator: SKY12361-350LF

Four-Bit Digital Attenuator: SKY12361-350LF

The SKY12361-350LF is a GaAs pHEMT four-bit broadband digital attenuator featuring an operating frequency of 0.1 to 3.7 GHz, and 15 dB attenuation with 1 dB least significant bit (LSB). This digital attenuator is ideal for a wide variety of cellular 3G and 4G infrastructure applications.

Switch Matrices

Switch Matrices

Switch matrices are typically used in the design verification or manufacturing phase of test systems. They’re designed to move signal routing and signal conditioning to a test system’s central location. This makes the characterization of the calibration plane between the DUT and the test equipment simpler, reduces insertion loss, improves signal integrity, and better controls phase issues. They can be used in both commercial wireless and aerospace/defense settings. This page provides an overview of Dow-Key Microwave’s offerings as it relates to switch matrices.

L-Band Attenuators

L-Band Attenuators

ETL Systems offers a series of attenuators with operating frequencies ranging in the L-band (850-2150 MHz), and are available with either 50Ω or 75Ω impedances specifically tailored to the respective connector types. Attenuation levels range from 3 to 20 dB, and come in DC block, DC pass, DC block & 10 MHz pass, DC pass & 10 MHz pass, DC block & 10 MHz block, and DC pass & 10 MHz block on all ports. Field applications for these l-band attenuators include telecom infrastructures, satellite systems, microwave links, test and instrumentation, military communications, and radar networks.
