K-HC1 RADAR TRANSCEIVER

Datasheet

Programming

Programming is necessary only for special applications of K-HC1. For normal operation as Doppler

Sensor is no need to program anything.

Some important parameters of the K-HC1 transceiver are configurable by an USB interface. It is also

possible read back the received RF power.

New settings can permanently be stored in the EEPROM of K-HC1.

Communication takes place via a serial protocol, that can be handled by any terminal software.

To store new parameters permanently: e <Enter>

Special Functions

Please refer to the application notes at the end of this document for more details.

Carrier OFF

Transmitter can be completely switched off, while the internal receiver oscillator is still active. This is

interesting, if using K-HC1 as pure superhet receiver.

PLL Reference external

Instead of using the internal 10MHz oscillator, an external oscillator may applied to connector “PLL”.

This allows generating FM for FMCW operation of the K-HC1.

Modulation external

Carrier my be modulated by an external signal applied to connector “Mod”. This allows e.g. generating

small frequency steps for FSK operation.

Ext Reference

Optionally, a 100MHz instead of a 10MHz reference may be used. This is interesting when using K-

HC1 as high performance receiver or as downconverter for a spectrum analyzer.
