Figure 2 shows the typical bench setup used to evaluate the performance of the ADRF6820. POWER SUPPLY The ADRF6820 evaluation board requires a quiet 6 V power source. This 6 V power source feeds the power supply design on the ADRF6820 evaluation board that consists of switches and dc regulators. Via the switches and/or dc regulators, 3.3 V and 5.0 V power rails are provided to the main IC. The high isolation 2:1 RF switch and on-chip tunable RF balun enable the ADRF6820 to support two single-ended, 50 Ω terminated RF inputs. The 2:1 RF switch can be controlled serially via the SPI port or in parallel via Switch S1. The default configuration is parallel control using the switch. The operational frequency range of the RF inputs is from 695 MHz to 2700 MHz; these inputs should be ac-coupled.

ADRF6820 Typical Measurement Setup Rev. 0 | Page 3 of 20 11993-002 DIFFERENTIAL I AND Q OUTPUTS RF INPUTS UG-652 EVAL-ADRF6820 User Guide The ADRF6820 offers two alternatives for generating the differential local oscillator (LO) input signal: • • Generate the signal externally via a high frequency, low phase noise LO signal. Generate the signal internally via the on-chip Fractional-N synthesizer. transformer/balun roll-off. However, to terminate the ADRF6820 with 200 Ω and also match the output impedance of the transformer with 50 Ω, an L network is placed between the I/Q outputs and the transformer. This introduces some power loss because the L network acts as a voltage divider (see Figure 3). The power loss due to the L network is approximately 17 dB. BBIN C64 0.1µF R33 0Ω DNI In either case, the differential LO signal can be routed off chip to SMA connectors labeled LOOP and LOON for the purpose of daisy-chaining multiple ICs requiring LO signals. For an internal LO configuration using the on-chip Fractional-N synthesizer, apply a low phase noise reference signal to the REF_IN connector. The PLL reference input can support a wide frequency range because the divide or multiplication block can be used to increase or decrease the reference frequency to the desired value before the signal is passed to the phase frequency detector (PFD). The integrated synthesizer enables continuous LO coverage from 356.25 MHz to 2850 MHz. For optimum performance using an external LO source, the LO input pins (LOIN− and LOIN+) should be driven differentially. The wide input range of the external LO inputs span from 350 MHz to 6000 MHz. Unless an ac-coupled balun/transformer is used to generate the differential LO, the inputs must be ac-coupled. The input impedance of the differential LO signals is 50 Ω. QUADRATURE I/Q OUTPUTS On the evaluation board, the quadrature I/Q outputs are terminated with 200 Ω differential. This is achieved by using a 1:1 transformer and an L-impedance matching network. The 1:1 transformer, TC1-1-13M+ from Mini-Circuits, is a very wide bandwidth (4.5 MHz to 3000 MHz) transformer that allows a flat pass-band response of up to 1 GHz. Using a wide bandwidth transformer is necessary to accurately evaluate the wideband pass-band response of the ADRF6820 without the effects of the R37 86.6Ω BBIN1 1 R41 32.4Ω R49 0Ω DNI 5 4 3 2 6 BBIP C63 0.1µF T6 1 R45 0Ω PRI SEC 4 3 R46 0Ω TC1-1-13M+ R38 86.6Ω R34 0Ω DNI JOHNSON142-0701-851 R52 0Ω BBIP1 1 R42 32.4Ω R50 0Ω DNI BBIN R68 0Ω DNI BBIP 5 4 3 2 JOHNSON142-0701-851 11993-003 LO INPUT/OUTPUT Figure 3. I/Q Output Matching Network To avoid the power loss from the L network while achieving the proper impedance matching, a 4:1 impedance transformer, such as the TC4-1W+ from Mini-Circuits can be used in place of the TC1-1-13M+. This 4:1 impedance transformer allows the primary side of the transformer to be terminated with 200 Ω and the secondary side to be terminated with 50 Ω. The L network then becomes unnecessary and can be shorted out by replacing R35, R36, R37, and R38 with 0 Ω while R31, R32, R33, R34, R39, R40, R41, and R42 can all be DNI (do not install). Attention needs to be paid to the bandwidth of the transformer because impedance transformation transformers tend to have narrower bandwidths. The TC4-1W+ has a listed bandwidth of 3 MHz to 800 MHz; however, the 1 dB bandwidth is limited to 100 MHz. As a result, the roll-off of the transformer may distort the pass-band flatness of the ADRF6820, depending on which bandwidth configuration is used for the ADRF6820.
