New ceramic packaged SMD crystal filter

KVG proudly present new 2- and 4-pole crystal filters with center frequencies between 21.40 MHz and 140.00 MHz packaged within a small SMD case of only 7 mm x 5 mm. The insertion loss is less than 3 dB and stopband attenuation up to 50 dB is achieved. The shape factor varies between 2.2 and 5.5 mainly depending on the number of poles.

The package is hermetically sealed and RoHS compliant for lead-free reflow soldering. KVG can guarantee a very good shock and vibration hardness for application in wireless communication systems and measurement equipment.

The 4-pole filters require an external coupling capacitor Cc to interconnect the two filter sections

of the device.

New Precision OCXOs Provide Ultra Low Phase Noise (ULPN) and Low G-Sensitivity (LGS)

By the usage of self-manufactured noise-optimized SC-cut crystals and noise-minimized electronic circuits KVG’s engineers succeeded in designing new OCXOs what provide beside a very high frequency stability an exceptional ULTRA low phase noise (ULPN) and in addition low G-sensitivity (LGS).

For high-frequency crystal oscillators locked to a frequency-reference the phase-noise (PN) in the frequency-range above the PLL-loop bandwidth is particularly important, because phase-noise is determined by the locked oscillator and not by the reference-signal. The new 100 MHz OCXOs - O-30-ULPN-100M – gives a “Noise Floor” for better than -185 dBc/Hz at 100 kHz offset...

New Precision OCXOs provide Ultra Low G-Sensitivity (ULGS) and Low Phase Noise (LPN)

By the usage of self-manufactured noise-optimized 5th overtone SC-cut crystals and noiseminimized electronic circuits KVG’s engineers succeeded in designing new OCXOs what provide beside an exceptional ultra low G-sensitivity (ULGS) and a low phase noise (LPN) and in addition a high frequency stability.

The new 100 MHz OCXOs - O-30-ULGS-100M – have an exceptional good robustness against vibration – also known as microphony – this is very important for oscillators with good phasenoise, to avoid a significant performance impact due to “vibration-induced” phase-modulation. The dynamic G-sensitivity of the new OCXO is less than 0.1 ppb/g (1 x 10-10/g) for all axes, which m...

KVG’s new small size clock oscillator for extended industrial temperature range

KVG launches two new product series XO-25000E and XO-32000E for extended industrial temperature range with very small dimensions. For these crystal clock oscillators (XO) 3 different temperature ranges are available, which are not covered through usual standard products; following temperature ranges and stability-groups are available:

• -55 bis +125 °C ±50ppm • -40 bis +125+°C ±50ppm • -40 bis +105 °C ±40ppm This includes stability vs. temperature range, adjustment tolerance @ 25°C, stability vs. 5% supply voltage change and 5% load change and aging for the first year. Frequencies are available between 1.25 MHz and 100 MHz, with standard frequencies like 10 MHz, 20 MHz, 26 MHz, 50 MHz or 1...
