The MGA-81563 can be damaged easily, but you can buy (relatively cheap: https://s.click.aliexpress.com/e/_Dl4U7Yl) and replace them yourself. For more information about this procedure, please check https://www.onesdr.com/2020/04/09/how-to-fix-a-broken-hackrf/

The previous link has a very good reference picture:

RX problems

If you find on a strong signal such as an broadcast FM station that you select Amp as "0" and you get a signal and then select Amp "1" and you do not then this is a good sign that the RF Preamplifier u13 (MGA-81563) is damaged. This can happen if you use a stronger transmitter near to your HackRF.

It is possible to replace the damaged IC with simple tools (soldering iron, solder wick). First solder flood the damaged component to remove it, preferably protecting the surrounding. Clean the pads and replace the component:

TX problems

The same component , is used for TX in Hackrf ONE , which also can be damaged.

Although the MGA-81563 datasheet mention that its operational frequency range is from 100 MHz to 6 GHz. In general, we can transmit quite safely from HF (> 14 MHz onward) to Microwave area ,but be aware , That you should better not use maximum power set up below 100 MHz .

• And of course, prior to any TX with max RF power set up , you should better try to adjust telescopic antenna to aprox 1/4 of wave length (or rough close enough).
• And please take special care to not transmit to any low frequency (MF , ex 520 Khz to 1700 Khz ) with maximum power (GAIN 47, RF AMP = 1).Because in those low frequecny conditions, it is very easy to damage the TX IC .

REPLACING MGA-81563

Due to small SMD size ,and small IC pitch pins , it is highly recommended to use any optical magnifying glass support , and be aware, that it needs medium / advanced solder skills ability.

In case that your Hackrf ONE has a front-end metal shielding part. You will need to remove it , just by mechanical up pressure. The top metal shielding part is inserted to many shield can clips, similar to the below pictures :

Below is an example of the replacement procedure. First remove and clean the pads. This can be done with hot air or normal soldering iron:

For the orientation, you could use the text of the chip itself. It should be "up", pointing to the antenna jack of the HackRF:

Once tested that the new replaced IC works well , do not forget to attach the top metal shielding , inserting correctly that part to all shield can clips.
