Hamgeek Micro PA50+ (PA50 Plus) 50W 3.5MHz-28.5MHz HF Power Amplifier HF Amp with 1.3" OLED Screen
Hamgeek Micro PA50+ is an upgraded product based on Micro PA50. Compared with Micro PA50, it has the following upgrades:
1. The upgraded display screen is a 1.3-inch OLED screen, which has a larger display area and is clearer and more intuitive.
2. Upgrade the thermal runaway management design, and improve the thermal stability again under the original high stability characteristics.
3. With the support of the new thermal runaway management, the IMD performance is improved to a new height, and its signal quality is better.
4. With the new LPF design, the power output of each frequency band is more balanced.
5. Upgrade the software algorithm and the execution efficiency is higher.
6. Customized lengthened UHF-KYD RF connectors can use non-standard plug-in connectors.
7. Optimize some hardware structure designs to improve the ability to resist falling.
Hamgeek Micro PA50+ inherits all the advantages of Micro PA50 at the same time. It is a 50W intelligent portable shortwave power amplifier. With high-speed automatic transmission and reception switching, it can automatically switch between receiving and transmitting without using an external PTT control line. Similarly, Hamgeek Micro PA50+ also enables high-speed automatic switching of LPF filters, and there is no need to connect the band control line, any QRP shortwave radio station can be used perfectly. And it has perfect power and standing wave display and protection functions; voltage display and protection functions; temperature display and intelligent heat dissipation and temperature protection; and the CW semi-plug-in mode function has also been added; of course, it also supports the use of external PTT to control receiving and transmitting switch and band control line switch LPF filter, and support for ICOM band switching protocol and XIEGU brand band switching protocol at the same time.
