GENERAL DESCRIPTION
The ADG918/ADG919 are wideband switches using a CMOS process to provide high isolation and low insertion loss to 1 GHz. The ADG918 is an absorptive (matched) switch having 50 terminated shunt legs, while the ADG919 is a reflective switch. These devices are designed such that the isolation is high over the dc to 1 GHz frequency range. They have on-board CMOS control logic, thus eliminating the need for external controlling circuitry. The control inputs are both CMOS and
0 -10 VDD = 2.5V TA = 25C
LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless applications and general-purpose high frequency switching.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

The attenuation between input and output ports of the switch when the switch control voltage is in the ON condition. 1 dB compression point. The RF input power level at which the switch insertion loss increases by 1 dB over its low level value. It is a measure of how much power the ON switch can handle before the insertion loss increases by 1 dB. Third order intermodulation intercept. This is a measure of the power in false tones that occur when closely spaced tones are passed through a switch, whereby the nonlinearity of the switch causes these false tones to be generated. The amount of reflected power relative to the incident power at a port. Large return loss indicates good matching. By measuring return loss the VSWR can be calculated from conversion charts. VSWR (voltage standing wave ratio) indicates degree of matching present at a switch RF port. Spurious signals present at the RF ports of the switch when the control voltage is switched from high to low or low to high without an RF signal present.

ADG918/ADG919 APPLICATIONS
The ADG918/ADG919 are ideal solutions for low power, high frequency applications. The low insertion loss, high isolation between ports, low distortion, and low current consumption of these parts make them excellent solutions for many high frequency switching applications. The most obvious application is in a transmit/receive block, as shown in the wireless metering block diagram in Figure 26. Other applications include switching between high frequency filters, ASK generator, FSK generator, and antenna diversity switch in many tuner modules. required isolation between the transmit and receive signals. The SPDT configuration isolates the high frequency receive signal from the high frequency transmit.

ABSORPTIVE VS. REFLECTIVE
The ADG918 is an absorptive (matched) switch with 50 terminated shunt legs, and the ADG919 is a reflective switch with 0 terminated shunts to ground. The ADG918 absorptive switch has a good VSWR on each port, regardless of the switch mode. An absorptive switch should be used when there is a need for a good VSWR that is looking into the port but not passing the through signal to the common port. The ADG918 is therefore ideal for applications that require minimum reflections back to the RF source. It also ensures that the maximum power is transferred to the load. The ADG919 reflective switch is suitable for applications where high off port VSWR does not matter and the switch has some other desired performance feature. It can be used in many applications, including high speed filter selection. In most cases, an absorptive switch can be used instead of a reflective switch, but not vice versa.
TUNER MODULES
The ADG918 can be used in a tuner module to switch between the cable TV input and the off-air antenna. This part is also ideal for use as an antenna diversity switch, switching different antenna to the tuner.

ADG918/ADG919 ADG9XX EVALUATION BOARD
The ADG9xx evaluation board allows designers to evaluate the high performance wideband switches with a minimum of effort. To prove that these devices meet the user's requirements, the user only requires a power supply and a network analyzer along with the evaluation board. An application note is available with the evaluation board and gives complete information on operating the evaluation board. The RFC port (see Figure 29) is connected through a 50 transmission line to the top left SMA connector J1. RF1 and RF2 are connected through 50 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 4-layer, FR4 material with a dielectric constant of 4.3 and an overall thickness of 0.062 inches. Two ground layers with grounded planes provide ground for the RF transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 0.052 inches, clearance to ground plane of 0.030 inches, dielectric thickness of 0.029 inches, and a metal thickness of 0.014 inches.
