The ADG901/ADG902 (SPST) and the ADG918/ADG919 (SPDT) are wideband switches using a CMOS process to provide high isolation and low insertion loss to 1 GHz. Full data on the ADG901/ADG902 and the ADG918/ADG919 is available in their respective data sheets available from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation board.

To prove that these devices meet the user’s requirements, use a power supply and a network analyzer. A 10 μF surface-mount tantalum decoupling capacitor is provided on the VDD line and two 10 pF ceramic capacitors are placed close to the DUT on both the VDD pin and the CTRL pin. Unpopulated component positions are available for the user to apply extra components to meet their design application. J6 This evaluation board has two analog power supply inputs: VDD and CTRL. VDD can equal 1.65 V to 2.75 V. C4 RF1 J2 RF2 C3 R1 C1 C2 RFC RF2 RF1 Table 1.

RF2 is connected through 50 Ω transmission lines to the top SMA connector, J2. The port labeled RF2 is ground; connect to ground when evaluating ADG901/ADG902. A through transmission line connects J4 and J5 and this transmission line is used to estimate the loss of the PCB over the environmental conditions being evaluated. J6 J7 VDD IN RF1 C4 J2 RF1 C3 RFC R1 C1 C2 RF2 RFC ADG918/ADG919 The RFC port, see Figure 3, is connected through a 50 Ω transmission line to the top left SMA connector, J1. RF1 and RF2 are connected through 50 Ω transmission lines to the top two SMA connectors, J2 and J3, respectively. A through transmission line connects J4 and J5 and this transmission line is used to estimate the loss of the PCB over the environmental conditions being evaluated. The board is constructed of a four layer, FR4 material with a dielectric constant of approximately 4.3. The total board thickness is 0.062”. Two ground layers with grounded planes provide ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide with the ground plane model using a trace width of 0.052”, clearance to the ground plane of 0.030”, dielectric thickness of 0.029” and a metal thickness of 0.0014”.
