    How can i learn the self resonance of a SMT capacitor ?

    cap self resonance With standard 0402 size capacitors you can approximate the model with a series inductance around 0.7nH. This is a raw approximation, but usually good for 1GHz range power decoupling. Personnally I use 33pF for 900MHz, 10pF for 1900MHz and 6pF for 2.4GHz. In order add some...

    Bluetooth RF Transceiver and baseband controler borad design

    Today most Bluetooth modules only have low layers up to HCI. Usually, these modules are connected to another CPU (PDA, Mobile phone, computer) which has the power and the memory to take care of the upper layers. One more thing is that as you know there is not one bluetooth protocol, you have a...

    REQ: S-PARAMETER FOR 2n2222 & 2n3904

    s parameter model for 2n3904 These are not small signal RF transistor. You can calculate the S parameters with spice. But you have to take the package into consideration. Infineon and Philips semiconductor web sites are good places to find spice models.

    What is the different GMSK and GFSK?

    dect system using gmsk Continuous phase FSK with modulation index equals to 0.5 is called MSK because phase shift is equal to pi/2 or -pi/2 every bit period. It is equivalent to differential binary PSK. With DECT for example, it happens when frequency deviation is exactly 288kHz. But DECT...
