ADL5519
Preliminary Technical Data
USING THE ADL5519
BASIC CONNECTIONS
The ADL5519 is specified for operation up to 10 GHz; as a
result, low impedance supply pins with adequate isolation
between functions are essential. A power supply voltage of
between 3.0 V and 5.5 V should be applied to VPSA, VPSB,
and VPSR. Power supply decoupling capacitors of 100 pF
and 0.1 μF should be connected close to these power
supply pins.

Figure 11. Basic Connections
The paddle of the LFCSP_VD package is internally
connected to COMR.
For optimum thermal and electrical
performance, the paddle should be soldered to a low
impedance ground plane.
INPUT SIGNAL COUPLING
The RF inputs (INHA and INHB) are single-ended and
must be ac-coupled. INLA and INLB (input common)
should be ac-coupled to ground. Suggested coupling
capacitors are 47 nF ceramic 0402-style capacitors for input
frequencies of 1 MHz to 10 GHz. The coupling capacitors
should be mounted close to the INHA[INHB] and
INLA[INLB} pins. The coupling capacitor values can be
increased to lower the input stage’s high-pass cutoff
frequency. The high-pass corner is set by the input coupling
capacitors and the internal 10 pF high-pass capacitor. The
dc voltage on INHA[INHB] and INLA[INLB] is about one
diode voltage drop below the supply voltage.

Figure 12. Single Channel Input Interface
While the input can be reactively matched, in general this is not
necessary. An external 52.3
Ω
shunt resistor (connected on the
signal side of the input coupling capacitors, as shown in
Figure 11) combines with the relatively high input impedance
to give an adequate broadband 50
Ω
match.
The coupling time constant, 50 × C
C
/2, forms a high-pass
corner with a 3 dB attenuation at f
HP
= 1/(2π × 50 × C
C
), where
C1 = C2 = C
C
. Using the typical value of 47 nF, this high pass
corner will be ~68 kHz. In high frequency applications, f
HP
should be as large as possible to minimize the coupling of
unwanted low frequency signals. In low frequency applications,
a simple RC network forming a low-pass filter should be added
at the input for similar reasons. This should generally be placed
at the generator side of the coupling capacitors, thereby
lowering the required capacitance value for a given high-pass
corner frequency.
TEMPERATURE SENSOR INTERFACE
The ADL5519 provides a temperature sensor output capable of
driving about 1.6 mA. The temperature scaling factor of the
output voltage is approximately 2 mV/°C. The typical absolute
voltage at 25°C is ~620 mV.
