... The on chip fixed capacitance is approximately 4.2pF. Wideband Mixer The RF2051 includes two wideband, double-balanced Gilbert cell mixers. They support RF/IF frequencies of 30MHz to 2500MHz using the internal VCO to provide the LO frequency of 300MHz to 2400MHz. Each mixer has an input port and an output port that can be used for either IF or RF, i.e. for up conversion or down conversion. The mixer current can be pro- grammed to between 15mA and 35mA depending on linearity requirements, using the MIX1_IDD< ...

... RF2051 for the data portion. RF2051 will read the data bits of the address on the rising edge of SCLK. After the address has been written, control of the SDATA line is handed over to RF2051. One and a half clocks are reserved for turn-around, and then the data bits are presented by RF2051. The data is set up on the rising edge of SCLK, and the controller latches the data on the falling edge of SCLK ...

... RF2051 Start-up When starting up and following device reset then REFSTBY=0, REFSTBY should be asserted high approximately 500μs before ENBL is taken high. This is to allow the XO to settle and will depend on XO characteristics. The various calibration routines will also take some time depending on whether they are enabled or not. Coarse tuning calibration takes about 50μs and VCO tun- ing gain compensation takes about 100μ ...
