MtronPTI, leader in precision frequency control and custom RF/microwave filters, today announced the TF0103 Low Insertion Loss 30 – 90 MHz Digitally Tuned Bandpass Filter and expanded their industry compatible tunable line spanning frequencies up to 1 GHz. Paul Dechen, MtronPTI Vice President of Worldwide Sales, says, “Digital RF communication is now the norm. As digital-to-analog and analog-to-digital conversion technologies move closer to the antenna, filter requirements change dramatically. Although demand will continue for custom crystal, ceramic, LC and cavity filters, the design focus at many of our clients is turning toward digitally tuned and switched filter arrays. The TF0103 Digitally Tuned Filter and our expanded frequency hopping line offer radio designers what they need: digital RF agility, extended radio range from a lower loss filter design and an industry compatible package.”
With over 500,000 tactical radios in service today, the Strategy Analytics Advanced Defense Systems (ADS) service report, “Ground Communications Systems and Components Forecast 2012-2022” July 1, 2013, forecasts land-based tactical radios to grow at about 7.2% CAGR to reach almost $4.5B. Handheld radios will be about 94% of shipment volume. Multi-band radios will grow fastest with electronic component growth at 14% CAGR, reaching $721M by 2022.
Paul continues, “Handheld radios typically dock in vehicle adapter amplifiers to boost radio range. These VAAs are where MtronPTI’s tunables fit – reducing cosite interference on the transmit side by limiting out-of-band emission and allowing increased sensitivity on the receive side by blocking nearby off-channel transmissions. MtronPTI’s TF010x series is pin compatible with industry standard MiniPole † filters while providing typically lower insertion loss and self-generated distortion. ”
Sampling now, the TF0103 30-90 MHz Digitally Tuned Filter supports the SINCGARS tactical radio band, providing 250 tuning steps of 240 kHz each with 25 µs switching time. Insertion loss is 3.6 dB with power handling in-band up to 1.25 Watts. Third order intercept (IP3) is +45 dBm minimum and out-of-band power can be up to 5 Watts @ ±10% off the tuned frequency.
