GENERAL DESCRIPTION
The parts have on-board CMOS control logic, thus eliminating
the need for external control circuitry. The control inputs are
both CMOS and LVTTL compatible. The ADG904/ADG904-R’s
low power consumption makes them ideally suited for wireless
applications and general-purpose high frequency switching.
The ADG904/ADG904-R are wideband analog 4:1multiplexers
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 isola-
tion is high over the dc to 1 GHz frequency range.
PRODUCT HIGHLIGHTS
1. –37 dB off isolation @ 1 GHz
The ADG904/ADG904-R switches one of four inputs to a
common output, RFC, as determined by the 3-bit binary

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may
affect device reliability. Only one absolute maximum rating may
be applied at any one time.
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.

ADG904/ADG904-R
APPLICATIONS
The ADG904/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 communication systems from
base stations to cell phones.

demands of devices transmitting at ISM band frequencies to
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 make
them cost effective and easy to integrate switching solutions for
many high frequency switching applications and low power
applications where the parts can handle up to 16 dBm of power.
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.

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.

Tx/Rx SWITCHING
The low insertion loss and high isolation between ports ensures
that the ADG904/ADG904-R is a suitable transmit/receive
switch for all ISM band and WirelessLAN, providing the
required isolation between the transmit and receive signals.
The ADG904-R 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.

ANTENNA DIVERSITY SWITCH
The ADG904 is ideal for use as an antenna diversity switch,
switching in different antennas to 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.
To prove that these devices meet the user’s requirements, only a
power supply and a network analyzer, along with the evaluation
board, are required. An application note available with the
evaluation board gives complete information on operating the
evaluation board.
The RFC port (see Figure 29) 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.
Figure 29. ADG904/ADG904-R Evaluation Board Top View
The board is constructed of 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 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.
