โมดูล RF TX เครื่องส่งสัญญาณ COFDM 70Mhz 80Mhz 150Mhz 160Mhz

Does your RF TX module COFDM transmitter support operating down to 150 MHz or lower?

Now we have noted it supports 200 MHz~2300MHz. According to the description of the TX module datasheet, it is not recommended to operate below 200MHz. Let’s take the board and test it later to see if it works.

ไอวีแคน: Our engineer has tested the RF TX module COFDM transmitter pcba. The minimum or lowest frequency can reach 70Mhz, but our receiver minimum range of 160Mhz and up to 860Mhz.

If you set the TX module at 70Mhz, then an Up-conversion board is required.
The lower the frequency, the greater the transmission power.
A PA power amplifier of less than 200 megabytes will be larger.

ไคลเอนต์: For the current request, the 160Mhz is good, so without an Up-converting board.
We use low power from the TX module and after we use our own PA, so it is not your question. We need an output of the Tx of about -10dBm.

ไอวีแคน: At 160MHz, the maximum output of the transmitter module is between -3dBm and -5dBm. แน่นอน, it can also be set to -10dBm through AT commands or the parameter board.

ไคลเอนต์: -5dBm is good, Please test it at -5 dBm output of Tx module.
