Secondly, I would also like to know if the TRW-400B includes an external LNA. I see some parts that look like an LNA (not the LNA in the CC1020) - so can you ask your engineers if they added an external LNA on the board?
1. TRW-400B already have LNA. 2. If you still need to add LNA, please deal with this part by yourself since we don’t know this extra LNA will cause any affect or not. We need to remind you this point in advance. Can you ask your engineers if they have measured the TRW-400B`s actual sensitivity performance (at 9600baud). I know what the datasheet says but I want to know if you have made in-house measurements of the sensitivity.
Around -115dBm. Yes, that is the modification that I want made. So basically what I want is a TRW-400B: 1. with NO MCU soldered in 2. with the wire connections shown in the photo I sent you 3. for half of the boards, with no SMA connector installed
TRW-400B is used software to adjust typical frequency, so our module is without any component parts to adjust frequency. If you ask us to take off MCU, you will not able to adjust typical frequency. Please confirm this. To use wireless transceiver modules to remotely control a fan, the applications are 1) Through a paired transceiver to and the reference of a control voltage --- DTMF, to control the fan. 2) Through a paired transceiver modules to build a long distance conversation. 3) To use transceiver modules as relay to enhance the distance of communication.
Please look into the modules below: 4) TRW-925A 5) TRW-V4B-V 6) TRW-400B I can not program your module trw-400 with a pic 16f873, my question is: what protocol must used the module I2c or SPI?, and what kind of bytes i have to send you to program this module as RX? because i have a lot of datasheet that are in contradiction to each other, and i do not understand them.

 No reply about this question. Como puedo usar en modo directo el TRW-400 , sin usar el I2C . ?Debo Usar los pines 1 Y 2 ?
Saludos. Estas trabajanddo con estos modulos? Ya estoy haciendo algunas pruebas. Te podes conectar por mi correo? gracias
