Description :

The FT-450D is a compact transceiver complete with an Automatic Antenna Tuner (ATU) weighing only 4kg. This lightweight package is designed to be used as a desktop radio or in portable applications. The FT450D can also be used car / mobile with the mobile bracket accessory (MMB-90). The rugged aluminum die-cast chassis with its quiet, thermostatically controlled cooling fan, provides a solid foundation for the 100 Watts push-pull power amplifier (with RDF100HHF1 MOSFET) on all HF bands (1.8 to 29.7 MHz) plus the low-VHF band (50 MHz). The FT450D IF-Width and IF-Shift features are the primary tools for best interference reduction, the IF-Contour control may also yield additional signal-enhancement benefits on the net residual bandwidth. The Contour filtering system provides a gentle shaping of the IF pass-band to suppress or enhance particular frequency components, thus improving the sound and/or readability of a received signal. This DSP filter is a unique capability of the receiver, providing either Nulling or Peaking of tunable segments to suppress interference and/or excessive frequency components on an incoming signal. The amount of Nulling / Peaking and the bandwidth over which it is applied are adjustable via the Menu. Of-course, the IF-Notch filter may also be utilized in conjunction with the other filter systems to significant advantage.

IF bandwidths :

Mode Nominal Adjustment range
CW 2.4 KHz 300 / 500 Hz / 2.4 KHz
Data 3.0 KHz 300 Hz / 2.4 / 3.0 KHz
SSB 2.4 KHz 1.8 / 2.4 / 3.0 KHz
AM 6.0 KHz 3.0 / 6.0 / 9.0 KHz
FM 9.0 KHz 9.0 / 15.0 KHz

Receiver block diagram :

A double conversion superheterodyne system with 8 band-pass filter for eliminate out of band strong interference. The RF amplifier with 2 x 2SK520 JFET, for high IP3, feed a 4-pole 10 kHz bandwidth roofing-filter in the 1° IF, just after the front-end mixer. This filter provides narrow-band selectivity to protect the following circuits. Then, the high performance DSP (400 MHz) at the 2° IF stage permits easy management of AGC, filters, noise reduction, for clear and quiet reception. The RF attenuator and preamplifier (IPO, Intercept Point Optimization) feature allow the operator to optimize the dynamic range window.
