RF & Wireless Products 8-Pin Dual-In-Line Mil-Spec High Reliability Crystal Oscillators Frequency control specialist, Euroquartz has added new 8-pin dual-in-line (DIL) models to its recently launched range of military specification crystal oscillators designed for use in applications that require high reliability. The new 8-pin DIL EQXO- 2000BM series clock oscillators complement the 14-pin DIL models – EQXO-1000BMK and EQXO-3000BMK –launched earlier this year and incorporate a custom-designed quartz crystal and a CMOS/TTL compatible hybrid circuit on a ceramic substrate. Manufactured using the latest advances in production technology, these oscillators are capable of achieving tight frequency calibration tolerance and high stability over a wide temperature range. Frequency range is from 30 kHz to 70 MHz with calibration tolerance of ±10 to ±25ppm at 25°C and frequency stability of ±100 or ±50ppm over the full military temperature range from -55 to +125 °C. The high reliability ceramic substrate is housed in an industry standard 8-pin DIL size oscillator package with four pins and a ruggedised three-point crystal mounting system within a hermetically sealed metal package. Additional specifications include ageing of ±3ppm maximum in first year, symmetry of 45%/55% and standard 5.0V DC supply voltage (other voltages on request). Standard output is CMOS, 50pF/10 TTL loads with other outputs available to special order. Ideal for upper atmosphere, aerospace, defence and other applications where high-reliability clock oscillators are required, the new EQXO-2000BM crystal oscillators can be screened to MIL-O-55310C, class B if required. Radiation tolerant EQXO-2000BMH versions will withstand ionising radiation to resist electrical failures for a total radiation dose of 40krad(SI). ■ Euroquartz Ltd info@euroquartz.co.uk www.euroquartz.co.uk 12 W S-Band Radar Amplifier RFMW Ltd. announces design and sales support for a surface mount GaN power amplifier from Qorvo. The Qorvo TGA2975-SM offers 12 W of saturated output power from 2.7 to 3.5 GHz. Small signal gain is >31 dB and input return loss is rated at >9 dB. The TGA2975- SM draws 175 mA from a 20...32 V bias supply with >52% power added efficiency (PAE). Serving Commercial and Defense Radar, the TGA2975-SM comes in a 5 x 5 mm, plastic QFN. ■ RFMW Ltd. www.rfmw.com 16 W X-Band Amplifier for PtP Radio RFMW Ltd. announced design and sales support for a 3-stage, highgain amplifier designed for ease-of-use in point-to-point radio systems. Featuring a frequency range of 9.5 to 12 GHz, the Qorvo TGA2760-SM offers 33 dB of gain from its 3-stage configuration. P1dB is up to 38 dBm while Psat is rated at 42 dBm. The TGA2760-SM is equipped with an integrated power detector and requires no external matching components. Developed using both GaAs and GaN it requires a 7 V source with up to 1,3 A and a 28 V source with 260 mA. Qorvo packages the TGA2760-SM in an 8 x 10 mm SMT laminate. ■ RFMW Ltd. www.rfmw.com hf-Praxis ISSN 1614-743X Fachzeitschrift für HFund Mikrowellentechnik • Herausgeber und Verlag: beam-Verlag Krummbogen 14 35039 Marburg Tel.: 06421/9614-0 Fax: 06421/9614-23 info@beam-verlag.de www.beam-verlag.de • Redaktion: Dipl.-Ing.
