    Need help to design low power supply final RF Power Amplifier

    Hi Tony & Ejunear, Here are some further details on my project: i) The 3 stage PA line up need to have high linear ouput at 36dBm. So each stage requires a minimum linear gain of 10dB ii) The existing predriver & driver stage is able to meet this spec but there is no final PA that can go up...

    Need help to design low power supply final RF Power Amplifier

    Hi folks, I'm trying to design a 3 stage PA line up consisting of pre-driver, driver & a final PA. The predriver & driver stage has been designed & my focus now is to design the final PA that needs the following goals to be achieved: 1) Power= 1.8 Watt or 2 Watt 2) Frequency range=...

    Need info about PC serial communication data buffer size.

    Re: Need info about PC serial communication data buffer size Hi IanP, Thanks for the info and link. However does the same buffer size apply for using activX components like MSCOMM for building GUI using softwares like Visual C++ or Visual Basic ?? or is it set to 4K bytes as i've mention in...

    Need info about PC serial communication data buffer size.

    Hi every1, I'm just wondering, wat is the data buffer size for most PC's serial communicatiom. when i tried to send a text file about 5 Kb using hyperterminal, i'm only receiving about 4Kb back to the PC for display.I even used other available GUIs like termV1.9 b and the same effect occurs...

    data errors due to line noise during serial transmission?

    hi guys, i'm just wondering wat causes data errors or data lost due to line noise for a serial communication? any other additional causes? So what is the best way to over come data errors or data lost?i know we can use CRC to settle this probelm but is it the best?

    Need sm explanation about Baud rate & serial comm

    Hi guys, I checked in da datasheet of PIC16f877 and i looked at TABLE 10-4 n i c dat there is baud rate error about 0.16% for a 20 MHz crystal which operates at 9.6kBaud. so i'm curious to know whether this small percentage of error could cost lost of bytes for a packet serial communcation...

    Not getting proper output for text file encryption

    Hi people, I recently posted a thread about data truncation problem with text file encryption. I overcame the problem by placing a delay function(sleep) in my pc application. However when i tried to encrypt a plain text file, i notice that sometimes there are missing bytes(1,2,3 or more...

    Need delay C routines to send serial data in VC

    Hi every1, I recently manage to implement the AES encryption algorithm into my PIC16f877. However when i send a text file larger than 16 bytes to my PIC using UART, the 2nd block data onwards is getting truncated. I very much think that i need to set a delay in my pc application so it sends...

    2nd block data truncated during encryption using PIC16f877

    data encryption&decryption using microcontroller hi every1, Just to make sure, i only make comparison with data in the RCREG once the RxBuffer is full with 16 bytes.So, the data in the RX Buffer is not compared to <CR> or <LF> characters.Only the byte that comes after the 16 byte is compared...

    2nd block data truncated during encryption using PIC16f877

    p16_tiri.asm Hi every1, Recently i posted a thread regarding text file encryption implementation in PIC16f877 using the AES algorithm.I was advised by ric to work with block of 16 bytes first before i could proceed with encryption.Eventually, i manage to send block of 16 byte serially by...

    Is this serial data transfer appropriate for encryption?

    p16_tprp hi every1, i wrote a pc application in Visual C which could send text file by block of 8 bytes.i short pin 2 and 3 of the serial port to test the GUI without any hardware.i was able to get back data by block of 8 bytes.any incomplete block is padded with a space character. Later i...
