Assuming gain error and offset errors to be 10% of full scale, then each contributes a 1 dB reduction in dynamic range. The DAC must be backed off 1 dB to prevent output clipping and another 1 dB to account for limited dynamic range. Add 2 dB dynamic range margin. • In aggregate:...
In FIG. 1, TX LO signal generator190generates the I and Q TX LO signals used for frequency upconversion, while RX LO signal generator180generates the I and Q RX LO signals used for frequency downconversion. Each LO signal is a periodic signal with a particular fundamental frequency. A PLL19...
ADC Dynamic Range Analysis. Digital to Analog Converter (DAC) performance is assessed in a similar fashion to ADC performance: • Sample rate Fsample is defined from the signal bandwidth which is 100 MHz in the RF domain or 50 MHz for I and Q each. Given 3GPP sample rates in multiples...
Power amplifier pre-distortion signal generator using an analog baseband envelope feedback loopPresented are methods and apparatuses for maintaining a substantially constant gain and reducing gain compression (AM-AM distortion) of a power amplifier based on a pre-distortion signal generated from an ...
a preamble generator21, a header generator22and an interface to a pay load data source23. In this application the expression “data” is used for all kinds of data no matter as to whether they are received from the preamble generator21, the header generator22or the pay load data source23...

A system comprises at least one of a first generator, at least two of a second generator, and a load board. The at least one of a first generator one of receives and transmits analo
The sample clock generator 23 preferably includes a crystal oscillator capable of frequency control over a relatively narrow range for generating cissoidal oscillations at a multiple of symbol rate. A symmetrical clipper or limiter generates a square-wave response to these cissoidal oscillations to gene...
