Raditek’s dielectric resonator oscillators, or DROs, are the industry standard for superior frequency stability and minimal phase noise.

Additionally, its small size makes it ideal for use in circuits with limited space, and the choice of internal or external phase locking gives our dielectric resonator oscillators even more stability.

We configure cutting-edge dielectric resonator oscillators using high-performance devices and are engineered to provide a wide range of frequencies from 3 MHz to 42 GHz with standard or custom options and a stability of 5 ppm.

However, the resonant frequency of the dielectric resonator oscillators can vary based on the variance in the bias voltage capacitance of the varactor.

Raditek’s dielectric resonator oscillators outperform other oscillators in terms of frequency pulling factor (the oscillator’s sensitivity to VSWR fluctuations). Moreover, dielectric resonator oscillators have a high Q-factor and a low phase noise, and they also exhibit superior thermal stability.

Our DROs are also typically used in electronic components like band-pass and band-stop filters, antennas, frequency measure meters, frequency selective limiters, and phased equalization applications.

Raditek provides a wide range of dielectric resonator oscillators that are suitable for all applications, which offer greater stability and power efficiency as compared to free-running cavity oscillators.

A low noise amplifier, also called LNA, is a frequency amplitude booster device compulsorily used in all the electronic communication receiver systems. It amplifies low-powered radio/microwave frequencies received from the outdoor/indoor antennas without degrading the signal-to-noise (SNR) ratio.

A low-noise amplifier’s job is to enhance the amplitude of weak input signals to the appropriate strength for subsequent processing, without causing any additional noise.

Articulately designed low noise amplifier from Raditek boosts the amplitude of weak signals by 20 decibels while keeping the noise figure (NF) below 1 dB.

The state-of-the-art low noise amplifier from Raditek is configured using low noise components, operating and biasing points, and related circuit topologies, which eliminates distortion-causing rogue frequencies that interfere with the ground-based receivers in the required manner, which debases the accuracy of output signals.

Cutting-edge LNAs from Raditek are designed and configured with high input/output impedance match and JFETs and HEMTs, which significantly reduces the relative shot noise or other system noises in the “Gain” created by the low noise amplifier.

With their ultra-low TT series, which offers up to -92 dBc performance and quality output with the lowest noise factor, gain, and impedance matching without sacrificing other crucial parameters, Raditek’s low noise amplifiers can handle extremely high-powered signals and greatly reduce IMD.

A steal! At a compelling price!

The advanced Raditek bandpasses provide excellent out-of-band rejection outside the targeted passband. It provides a narrow bandwidth and a high Q-factor for more selective filtering, resulting in improved performance by decreasing noise and interference.

Raditek’s band pass filter is designed for consistent and stable performance throughout a wide range of temperatures, allowing it to retain the essential performance levels in any thermal condition.

Furthermore, our band pass filters have a tiny dimensional footprint, making them ideal for mobile and other telecommunications equipment. A Raditek-designed band pass filter reduces frequency power loss, which is common in bandpass filters, which are predominantly used in systems needing frequency band change for various frequency receptions.

Raditek provides a large selection of the best-in-class band pass filters, including all-pass filters that pass all frequencies while changing the phase relationship to delay or correct signals, time-variant-invariant filters, active/passive filters, non-linear filters, and linear filters.

Raditek provides the best ready-to-use bandpass filters, and also offers to customize a band pass filter.
