PRODUCTS

Bandpass Filter Series Bandpass Filter Series

DLI microstrip bandpass filters offer classical filter topologies yielding excellent performance in a small footprint when fabricated on ceramic substrate materials. Miniaturization can reach new levels by employing DLI high-k ceramic materials.  Different techniques are employed to realize small size and high performance. Catalog devices come complete with integrated shielding and the surface mount versions are designed for use on most RF PWB materials.  Typical features include center frequency from C to K band although custom devices are available from 1 to 60 GHz. Band pass filters pass desired frequency range and suppress the rest of undesired spectrum.

Wilkinson Power Dividers Wilkinson Power Dividers

Wilkinson dividers (3 dB per split) incorporating our low loss, high permittivity dielectric materials to provide small size and temperature stability.  The devices integrate thin film precision resistors and are offered for both solder surface mount (SMT) and chip and wire hybrid (WB) assembly applications.

Single Layer Capacitors For DC Blocking Or RF Bypass Applications Single Layer Capacitors For DC Blocking Or RF Bypass Applications

Dielectric Laboratories (DLI) offers a series of single layer capacitors designed with Class II dielectric materials and X7R temperature stability characteristics for a variety of DC blocking or RF bypass applications. With operation capabilities over a broad frequency range, these high frequency, wire bondable capacitors are ideal for GaN, GaAs, filtering, tuning, and coupling applications where small size and microwave performance is vital for a circuit’s performance.

Surface Mount Directional Couplers Surface Mount Directional Couplers

Dielectric Labs Inc. (DLI) introduces a series of surface mount directional couplers designed to offer a turnkey surface mount solution for high frequency incident and reflected power monitoring. These directional couplers span the C, X, and Ku band frequency spectrums, and are available with 10dB and 20dB coupling values, and a common footprint for maximum flexibility.

Broadband Blocking Components Broadband Blocking Components

DLI offers many options for your broadband blocking needs that range from DC to greater than 40 GHz. This page provides an overview of their broadband blocking components.

Surface Mount Lowpass Filter Series Surface Mount Lowpass Filter Series

DLI’s series of surface mount lowpass filters are compact and fully shielded. They feature frequency stability over temperature, excellent repeatability, 50Ω characteristic impedance, and a -55oC to +125oC operating temperature.

DC-18 GHz Gain Equalizers: EW Series DC-18 GHz Gain Equalizers: EW Series

These equalizers have been designed for use as a compensation circuit to correct for the loss slope that can be sometimes be created by other circuit elements. They’re ideal for integration into EW, ECM, and ECCM broadband microwave modules.

Hi Q Single Layer Capacitors Hi Q Single Layer Capacitors

DLI has made a name for themselves through manufacturing high Q, high frequency single layer capacitors that feature gold metallization for wire bonding, thin film technology, and rugged construction. They’re ideal for high frequency applications such as DC blocking, tuning, RF bypass, and filtering.

Mini Temperature Stable Filters Mini Temperature Stable Filters

DLI’s engineers select from numerous filter topologies to solve your frequency management problem. We have expanded capability beyond band pass designs to include notch filters, low pass and high pass filters and band stop filters and other passive devices such as dividers and couplers. Designs are customized to your requirements to offer performance, size and repeatability.

Gain Equalizers: EW Series Gain Equalizers: EW Series

DLI’s Gain Equalizers are designed as a small, low cost solution to your gain slope challenges. DLI’s EW series is designed to address this issue from DC to 18 GHz in a package smaller than an 0302 capacitor. Components are designed for surface mount pick and place equipment or epoxy mount. Available in tape and reel packaging for high volume applications.
