The parts have on-board CMOS control logic, which eliminates
the need for external control circuitry. The control inputs
are both CMOS and LVTTL compatible. The low power
consumption of these devices makes them ideally suited
for wireless applications and general-purpose high
frequency switching.

The ADG904 and ADG904-R switch one of four inputs to a
common output, RFC, as determined by the 3-bit binary

Figure 1.
The ADG904 and ADG904-R are wideband analog 4:1
multiplexers that use a CMOS process to provide high isolation
and low insertion loss to 1 GHz. The ADG904 is an
absorptive/matched mux with 50 Ω terminated shunt legs; the
ADG904-R is a reflective mux. These devices are designed such
that the isolation is high over the dc to 1 GHz frequency range.

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.

Rise Time. Time for the RF signal to rise from 10% of the on level to 90% of the on level.

Transition Time. Delay between applying the digital control input and the output switching on.
The Attenuation between Input and Output Ports of the Switch when the Switch Control Voltage is in the Off Condition.
The Attenuation between Input and Output Ports of the Switch when the Switch Control Voltage is in the On Condition.
Measure of Unwanted Signal Coupled through from One Channel to Another as a Result of Parasitic Capacitance.
1 dB Compression Point. The RF input power level at which the switch insertion loss increases by 1 dB over its low level
value. P–1 dB 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, and 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 voltage standing wave ratio (VSWR) can be calculated from conversion charts. VSWR indicates
the 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.

ADG904/ADG904-R
APPLICATIONS
The ADG904 and ADG904-R 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. They may be used
in applications such as switchable filters, transmitters and
receivers for radar systems, and communications systems from
base stations to cell phones.
ABSORPTIVE VS. REFLECTIVE
The ADG904 is an absorptive (matched) switch with 50 Ω
terminated shunt legs; the ADG904-R is a reflective switch with
0 Ω terminated shunts to ground. The ADG904 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 ADG904 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 ADG904-R reflective switch is suitable for applications
where high off port VSWR does not matter, and the switch has
other performance features. It may be used in many applications, including high speed filter selection. In most cases, an
absorptive switch may be used instead of a reflective switch, but
not vice versa.

FILTER SELECTION
The ADG904 can be used to switch high frequency signals
between different filters and to multiplex the signal to the
output. These SP4T switches are also ideal for high speed
signal routing.

The ADG9xx wideband switches are designed to meet the
demands of devices that transmit at ISM band frequencies of
1 GHz and higher. The low insertion loss, high isolation
between ports, single pin control interface, no requirement for
dc blocking capacitors, and TTL interface compatibility of these
parts make them cost-effective and an easy-to-integrate
switching solution for many high frequency switching
applications and low power applications where the parts can
handle up to 16 dBm of power.

Tx/Rx SWITCHING
The low insertion loss and high isolation between ports ensure
that the ADG904 and ADG904-R are suitable transmit/receive
switches for all ISM band and wireless LAN, providing the
required isolation between the transmit signal and the
receive signal.

The ADG904 is ideal for use as an antenna diversity switch,
switching different antennas into the tuner. The low insertion
loss ensures minimum signal loss and high isolation between
channels, making these SP4T switches suitable for switching
applications in tuner modules and set-top boxes.

EVALUATION BOARD
The ADG904/ADG904-R evaluation board allows designers
to evaluate the high performance, wideband switches with
minimal effort.
The RFC port (see Figure 30) is connected through a 50 Ω
transmission line to the bottom left SMA connector, J4. RF1,
RF2, RF3, and RF4 are connected through 50 Ω transmission
lines to SMA connectors J5, J6, J7, and J8, respectively. A through
transmission line connects J9 and J10; this transmission line
is used to estimate the loss of the PCB over the environmental
conditions being evaluated.
The board is constructed of four-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 a ground plane model using
a trace width of 0.024 inches, clearance to ground plane of
0.008 inches, dielectric thickness of 0.02 inches, and a metal
thickness of 0.0021 inches.

Only a power supply and a network analyzer, along with the
evaluation board, are required to demonstrate that these devices
meet user requirements. An application note, available with the
evaluation board, provides complete operating information.
