The receive path consists of a fully differential I/Q baseband PGA, low-pass filter, and general signal conditioning before connecting to an Rx ADC for baseband conversion. The Rx LPF gain ranges from 3 dB to 24 dB, programmable in 3 dB steps. The Rx LPF features four programmable modes with cutoff frequencies of 330 kHz, 880 kHz, and 1.76 MHz, or the filter can be bypassed if necessary. 900 MHz ISM Band Analog RF Front End ADF9010 RxINIP RxININ RxCM RxINQP RxINQN MUXOUT RSET CP VTUNE LOOUTP LOOUTN TxOUTP TxOUTN FUNCTIONAL BLOCK DIAGRAM RXVDD AVDD VP DVDD CE VCM ADF9010 VCM DC OFFSET CORRECTION RxBBIP RxBBIN OVF DC OFFSET CORRECTION CHARGE PUMP PHASE FREQUENCY DETECTOR R COUNTER B COUNTER A COUNTER ÷4 QUADRATURE PHASE SPLITTER 24-BIT INPUT SHIFT REGISTER PLL N COUNTER N = BP + A PRESCALER P/P + 1 DGND AGND Figure 1.

It converts a baseband I/Q signal to an RF carrier-based signal between 840 MHz and 960 MHz. The highly linear transmit signal path ensures low output distortion. Complete local oscillator (LO) signal generation is integrated on chip, including the integer-N synthesizer and VCO, which generate the required I and Q signals for transmit I/Q upconver- sion. The LO signal is also available at the output to drive an external RF demodulator. Control of all the on-chip registers is via a simple 3-wire serial interface. The device operates with a power supply ranging from 3.15 V to 3.45 V and can be powered down when not in use. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.

The spectrum analyzer provides the REFIN for the synthesizer; offset frequency = 1 kHz. 4 fREFIN = 10 MHz; fPFD = 1000 kHz; N = 3600; loop BW = 25 kHz. 5 Guaranteed by design. Sample tested to ensure compliance. 6 This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the RF input is divided down to a frequency that is less than this value.
