General Description
Pin Configuration
The TQP4M9083 is a high linearity, low insertion loss, 7-bit,
31.75 dB Digital Step Attenuator (DSA) operating over the
0.4–3.5GHz frequency range. The digital step attenuator uses
a single positive 5V supply and has a serial periphery
interface (SPITM) for changing attenuation states. This
product maintains high attenuation accuracy over frequency
and temperature. No external matching components are
needed for the DSA.
The TQP4M9083 is available in a standard lead-free
/green/RoHS-compliant 24-pin 4x4mm QFN package. The
TQP4M9071 and TQP4M9072 are also available from
TriQuint as a footprint and pin compatible 6-bit, 31.5dB DSA
with a parallel control interface and serial control interface
respectively.

Description
Clock. This serial clock is used to clock in the serial data to the registers. The data is latched
on the CLK rising edge. This input is a high impedance CMOS input.
Serial Input Data. The 7-bit serial data is loaded MSB first. This input is a high impedance
CMOS input.
Latch Enable, When LE goes high, 7-bit data in the serial input register is transferred to the
www.DataSheet.net/
attenuator. When LE is high, CLK is disabled
RF Input, DC voltage present, blocking capacitor required. Can be used for Input or Output.
RF Output, DC voltage present, blocking capacitor required. Can be used for Input or Output.
Serial Output Data
Supply Voltage. Bypass capacitor required close to the pin. Dropping resistor highly
recommended ensuring compatibility with different power supplies.
These pins must be connected to RF/DC ground
These pins are not connected internally but can be grounded on the PCB
Multiple vias should be employed for proper performance; see page 10 for suggested footprint
