- Down conversion employed for all Amateur Radio bands (main receiver) -Newly developed mixer contributes to IP3 +40dBm performance (main receiver) – New narrow-band high-IP roofing filters help to remove adjacent interference (main receiver)
- New VCO division-type first local oscillator divides high frequencies to ensure high C/N – ±0.1ppm TCXO ensures both high stability and reduced power consumption – Sub receiver down conversion on main Amateur bands below 21MHz range
- Dedicated triple DSP’s for main&sub receivers plus band scope. – Advanced AGC (Auto Gain Control), digital and analog – Extensive interference/noise removal features
- Robust design delivers stable operation at 200W – Internal automatic antenna tuner enables rapid tuning – Cooling system capable of providing ample airflow to each unit
- Dual TFT display offers excellent visibility – New frequency function for intuitive operation – New split function for quick configuration – Memory accessible even during split/sub receiver operation – Remote PC operation of TS-990 Series – Data modes facilitate switching between external terminals – Enhanced convenience with 2 USB sockets on the front panel
The new TS-990 is equipped with dual receivers to enable simultaneous reception on two different bands. The main receiver employs full down conversion and features a new mixer and narrow-band roofing filters, resulting in a third-order intercept point of +40dBm; this represents the highest level of RX performance. Also equipped are triple 32-bit floating point DSPs and an original IF AGC circuit featuring leading-edge DSP technology. Advanced KENWOOD technologies deliver the top-end RX performance that DX’ers are looking for in an HF transceiver. Moreover, 50V MOSFETs are used for the final amp, ensuring stable high-output operation with minimal distortion, even at 200W RF output power. All this and more: the world’s first*1 dual TFT display – with a band scope, audio scope, and S meter – offers enhanced visibility and operating ease.
