General Description
The TQM829007 is a digital variable gain amplifier
(DVGA) featuring high linearity performance in a fully
integrated module. The amplifier module features the
integration of a low noise amplifier gain block, a digital-
step attenuator (DSA), along with a high linearity ¼W
amplifier. The module has the added features of integrating
all matching components with bias chokes and blocking
capacitors. The internal DSA offers 0.5 dB step, 6-bit, and
31.5 dB range and is controlled with a serial periphery
interface (SPI
TM
).
The TQM829007 features variable gain from 0 to 31.5 dB
at 0.9 GHz, has +40 dBm Output IP3, and +24.3 dBm
P1dB. The amplifier also has a very low 2.1 dB Noise
Figure (at maximum gain) allowing it to be an ideal DVGA
for both receiver and transmitter applications.
The
amplifier operates from a single +5V supply and is
available in a compact 28-pin 6x6 mm leadless SMT
package.
The TQM829007 is pin compatible with the TQM879006
(1.4-2.7GHz, 0.25W DVGA) and TQM879008 (1.5-2.7
GHz, 0.5W DVGA). This allows one to size the right type
of device for specific system level requirements as well as
making the DVGA family ideal for applications where a
common PCB layout is used for different frequency bands.
