    Hi all. We are also working in a design involving cc2590, we purchased some cc2430-cc2590EMK in order to evaluate this amplifier. The emk has that L21 mounted, but there is no information about its value. It seems to be the same type of inductor and, maybe, same value (?) than L111 (2.2nH). ...

    Hello Ghasem, I am sorry for the late answer. Cadstar is not optimum with respect to exporting data to other formats. You may however use this program to convert files: http://www.linkcad.com/ , or you could use the freeware version of Cadstar called Cadstar Express, www.zuken.com , to alter...

    Estimate the NF of an RX system by using BER By measuring a system BER performance for a given bit rate and knowing the RX filter bandwidth it is possible to solve for system noise figure. First we need to know calculate the back ground noise level over a given bandwidth. This determines the lower...

    We have 2 identical boards, each having a CC2510 and a CC2590, manufactured (by our customer) to the TI recommended layout, as far as I know. The high gain pin on the CC2590 is asserted. We have one of these set up at present as a transmitter, sending a packet once every 1.6ms at a fixed carrier approximately...

    Hello, I'm doing a CC2530 + CC2590 (NOT CC2591) design and am looking for a reference design. I went to the CC2590 page and saw a reference design for the CC2591 with the CC2530 (AN086) but none for the '90. I'm hesitant to just apply the '91 reference design because IIRC the cc2590...

    Hung
    Hi all, I know that the antenna of of CC259x (pin 11) should be connected to Vcc pin through Tline (inductor) in Tx mode so there is a DC net level in this pin. Right? How about the connection on Rx mode for LNA, is there a same DC level as Tx mode? If then, a series capacitor needed to include...

    Hello, In the CC2590/CC2520 reference design the CC2590's RXTX pad is NC. In my design's 1st production batch I measure ~3Ohm between this pad and GND. Is it a problem? Can I overcome this error with different settings for the various control lines? Thanks, Lior
