Adjustable Key-Press Attenuator Step-Adjustable RF Attenuator (5W SMA 0-90dB)

3GHz with good bidirectional performance. Purchased to perform LTE signal margin testing for a cellular IoT product, and tested using HP8596E from 0-100. Using a tracking generator, we were able to achieve a frequency of 3GHz Individually and in combination, each button provides a close match to the marked attenuation. I measured about 2dB insertion loss in my overall setup, which consisted of two 1 meter cables and an attenuator from the tracking generator output to the SA input (loss of the attenuator was not measured separately). The construction appears to be of good quality. br>br> I measured again after pressing the buttons 10 times (on/off) to see if there was any variation in loss. There was no discernible difference.

Examining the Key- (5W N 0-) Press Attenuator (90 decibels). The construction of this unit is excellent. After being put to the test, it was discovered that it meets all of the advertised specifications- Attenuation, frequency response, and insertion loss are all steps in the process. The results of the tests showed that it complies with the advertised specifications. The only issue I found was that pressing the switches to add or remove attenuation causes the signal to drop for a brief period of time (abt 10-). 20ms). In most cases, this should not be an issue, but it is something that a user should be aware of. It could make a receiver click or power a small device. Crazy talkie. Aside from that, it's a well-made, long-lasting step attenuator with good performance. I'm the proud owner of two of them.

This is a very nice and small attenuator. It does exactly what it says it will and is a great addition to my RF equipment. The product was delivered on time and at a reasonable price. Another reviewer made an in-depth analysis of the product. There is no need to repeat such tests because he has in-depth, valid data from his spectrum analyzer. br>For those who are curious, I included a look inside photo.

Expect 10 to 20 % inaccuracy on all positions from 10 to 20 % inaccuracy on all positions from 10 to 20 % Higher frequencies (above 100 Mhz) improve it slightly, but the values are fairly flat from 3 MHz to 500 MHz, which is the limit of my testing capability. If you can track down an old HP 355A (1-year warranty), you'll be in luck. 12 decibels) or 355B (10 decibels). You could get a better deal for less money if you lowered the decibel level to 120 dB.

Signal levels are set in SDR using this command. Only 50 Db was achieved by the previous attenuator. This one reaches a decibel level of 90.

It's small and compact, and the attenuation switches correspond to the unit's numbers. For the price, this is a fantastic product.
