Aaronia PowerLOG 50700

The Aaronia PowerLOG 50700 is a passive double-ridged horn antenna covering 5 GHz to 70 GHz. It has a 1.85 mm V (f) connector, measures 50 x 32 x 34 mm and weighs 50 g, and is suitable for both transmitting and receiving, and for EMC emissions work.

5 GHz to 70 GHz in a 50 g Horn

The PowerLOG 50700 covers 5 GHz to 70 GHz in a horn measuring 50 x 32 x 34 mm and weighing 50 g, with a 1.85 mm V (f) connector to carry the full range. It mounts on the supplied aluminium bracket. Aaronia states that the gain of its standard PowerLOG horns rises with frequency to a maximum of about 25 dBi, which offsets the rising cable loss at higher frequencies. The technical datasheet gives return loss, VSWR, gain and antenna factor as plots, and the -3 dB beamwidth as a table.

Compact Microwave Horn

At 50 x 32 x 34 mm and 50 g, the PowerLOG 50700 is small enough to sit close to a device under test.

Calibration Data Included

Aaronia states each PowerLOG is delivered with high-resolution calibration data (certificate and download link to an Excel file). With the antenna factor applied, the spectrum analyser reading converts to field strength, and in transmit use the gain figures let you work out the field strength produced at the test distance.

Specifications

Limitations

• Aaronia's datasheet gives no maximum input power for the 50700, and states its gain only as a maximum of 25 dBi. Ask us before using it to transmit at high power.
• A horn is directional: it must be aimed at the device under test, and its coverage at short distances is limited by the beamwidth.
• Transmit use is subject to local radio regulations.

PowerLOG Range Compared

Typical Applications

EMC and interference emission measurements, and receive measurements on microwave and millimetre-wave devices with a spectrum analyser or oscilloscope, where a small horn can sit close to the device.

The PowerLOG 50700 suits EMC test engineers and RF and microwave engineers who need a calibrated horn for 5 GHz to 70 GHz.

Frequently Asked Questions

Which PowerLOG Model Do I Need?

Choose by frequency range. The 10800 covers 1 GHz to 8 GHz, the 70180 700 MHz to 18 GHz, the 40400 4 GHz to 40 GHz and the 50700 5 GHz to 70 GHz. The 70180 has the highest published power rating (500 W peak), followed by the 10800 (400 W peak); Aaronia gives no rating for the 50700.
