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 Ω terminated shunt legs, whereas 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 LVTTL compatible. The low power consumption of these CMOS devices makes them ideally suited to wireless and general-purpose high frequency switching applications.

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. Return Loss 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 (voltage standing wave ratio) can be calculated from conversion charts. VSWR indicates the degree of matching present at a switch RF port.

The SPDT configuration isolates the high frequency receive signal from the high frequency transmit. LNA ANTENNA ADG918 Other applications include switching between high frequency filters, an ASK generator, an FSK generator, and an antenna diversity switch in many tuner modules. TX/RX SWITCH 03335-005 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. PA Figure 26. Wireless Metering ABSORPTIVE VS. REFLECTIVE SWITCH 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. ANTENNA ADG918/ ADG919 CABLE TUNER 03335-006 VGA Figure 27. Tuner Modules FILTER SELECTION The ADG919 can be used as a 2:1 demultiplex to switch high frequency signals between different filters and also to multiplex the signal to the output. RFIN WIRELESS METERING The ADG918 can be used in wireless metering applications. It can be used in conjunction with the ADF7020 transceiver IC for Rev. C | Page 13 of 16 RFC ADG919 RF1 RF2 RF1 RF2 ADG919 Figure 28. Filter Selection RFOUT RFC 03335-007 The ADG918 is an absorptive (matched) switch with 50 Ω terminated shunt legs, and the ADG919 is a reflective switch with 0 Ω 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. ADG918/ADG919 ADG9xx EVALUATION BOARD The ADG9xx evaluation board allows designers to evaluate the high performance wideband switches with a minimum of effort. The RFC port (see Figure 29) 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 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, a clearance to ground plane of 0.030 inches, a dielectric thickness of 0.029 inches, and a metal thickness of 0.014 inches. Rev. C | Page 14 of 16 03335-008 In addition to the evaluation board, the user requires only a power supply and a network analyzer. An application note is available with the evaluation board and gives complete information about operating the evaluation board. Figure 29.
