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.
iVCan: 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.
Kliyente: For the current request, the 160Mhz is good, kaya walang Up-converting board.
Ginagamit namin ang mababang kapangyarihan mula sa TX module at pagkatapos naming gamitin ang aming sariling PA, kaya hindi ito ang tanong mo. Kailangan namin ng isang output ng Tx ng tungkol sa -10dBm.
iVCan: Sa 160MHz, ang maximum na output ng transmiter module ay sa pagitan ng -3dBm at -5dBm. Oo nga naman, maaari rin itong itakda sa -10dBm sa pamamagitan ng mga command ng AT o sa parameter board.
Kliyente: -5ang galing naman ng dBm, Paki test na lang ha -5 dBm output ng Tx module.
The waveform when output-5DBM is output during testing of TX module
Does your RF TX Module support 3.5G?
COFDM Video encoder modulator transmiter module 3.5G at 4G resulta ng pagsubok.
Can you send us your COFDM TX RX module with metal casing and power amplifier inside?
Oo, we can offer you the full set of COFDM TX RX modules with metal casing and power amplifier (1-watt PA, 2.5-watt PA, or 10-watt PA optional)r, and cofdm transmitter antenna and receiver antenna.
