TI’s new range extender looks interesting:

the 4.6 dB LNA noise figure is bad. But that’s what happens with cheap BDAs.

The noise figure can degrade the SNR of a weak signal so much that the LNA is a detriment.

I didn’t notice that, it is very high.

Hey Guys,

Kindly also look at RF Arrays Systems India, They too have a 20dBm high power solution which has be integrated with Jennic JN5139, Radio Pulse Mango MG2455, TI Chipcon 2250, Ember EM250 and Nordic Audio solution. its RX noise figure is also 2.2mentioned, actual 1.6dB and RX gain of 15dBm.

Samples of reference design boards are available.

Chipcons FEM has a limitation that it is tailored for CC24XX series only.

have fun,

cheers

Hi everyone !!!

I have just completed the schematic design for integrating AT86RF231 with External PA/LNA with 20dBm RF output power and Antenna Diversity. The PCB design is underway and I hope to ship samples by mid of May. Presently I am finding difficulty in finding AT86RF231 IC with most online vendors. Plz help in this regard. I intend to sell this module at $30 in retail.

I have also developed the following 2.4 GHz High Power RF Modules (18dBm):

  1. Nordic nRF24L01/L01+ : With external RF Front End (TRX IC + RF), SPI Interface @ $25 in retail.

  2. Jennic JN5139 : With external RF Front End (SoC + RF) @ $25 in retail.

  3. TI CC2430 : With external RF Front End (SoC + RF) @ $30 in retail.

  4. Radio Pulse MG2455 : With external RF Front End (SoC + RF) @ $30 in retail.

I am also looking forward to provide consulting and team-up for any design & development activity which involves integrating low power baseband SoC with External RF Front End/ PA/ LNA.

Kindly let me know if anyone is interested. I can be contacted at Email: info@rftrinity.com or at cell: +91-9860863334/+91-9561504646.

Happy to help !!!
