RF-schematics. Option attenuator is only required in case of LWA with high front-end gain. All other antennas (LPDA, Dipole, BICONE) don't require attenuator at the input. In case of an order, I need to know the type of antenna. |
| Dual channel heterodyne up-converter (DUpCon). | Description | US$ |
|---|---|---|
 |
Passive dual channel heterodyne up-converter to observe frequencies below the native frequency range of Callisto. This unit is meant as up-converter for LWA (LHCP and RHCP) to observe 10 MHz - 78 MHz. Local oscillator is quartz controlled at 175 MHz, some at 200 MHz. Output frequency range dedicated for Callisto: 185 - 253 MHz. For LWA applications, both channels are frequency- and phase synchronous. For single dipole applications we suggest another converter, as shown above. Power consumption: 12 volts, 130 mA ... 150 mA, ~1.8 watts. Weight: 1.3 kg Size: 257 mm x 170 mm x 55 mm Prize includes a 12 volt power adapter with international connector set. Depending on component availability, it may look slightly different inside. Stock: 2. Further production only on request. |

Combined LNA and heterodyne down-converter to observe frequencies above the native frequency range of Callisto. We can provide converter to observe solar radio bursts in L-band 1045-1600 MHz as well as GNSS signals, e.g. GPS and others. LNA and heterodyne-converter are mounted in one single aluminium-box (IP66) and are supplied via coax cable and via a Bias-Tee. Depending on component availability, it may look slightly different inside. Also local oscillator and frequency-range depend on componente-availability on the market. The image on the left shows the box without the option: 'Calibration Unit'. Other frequency ranges (S-band, C-band, X-band etc.) on request. Stock: 0, currently 4 in production for DLR. |

A Python script to automatically track the Sun is provided for free. Scripts to track Moon or other sources can be provided too. Mast or pole or rod is NOT part of delivery, needs to be organized by the user locally. Original axis are removed but part of delivery. Rotors are prepared to be mounted together. Prototype image on the left: P. Hirt, Muhen. Stock: 20 rotors to build up 10 dual-axis systems. Weight and size: 2 rotors à 2.7kg + mechanics 1.9kg + controller 0.8kg + optional cables minimum 9kg In case of shipping there is a box required, thus the total weight will be in the order of ~13kg. |

The same system as above but, here in off-axis mounting which requires less components. The weight is out off axis while the solution above takes care to get the moment more on-axis. The mechanical parts we provide allow both solutions, depending on customers needs. The above solution gives more freedom for the moving antenna while this (left image) solution has some restrictions for antenna movement. The user should decide which mounting version is best for his type of antenna and usage. Prototype image on the left: PI of e-Callisto.org, Freienbach/Switzerland. |
