TQM879008 1.4-2.7 GHz 1/2W Digital Variable Gain Amplifier Product Overview The TQM879008 is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. This amplifier module integrates two gain blocks, a digital- step attenuator (DSA), and a high linearity W amplifier. The module has the added feature of integrating all matching components, bias chokes and blocking 28-pin 6x6 mm leadless SMT Package capacitors. The internal 6-bit DSA provides a 31.5 dB gain control range in 0.5 dB steps, and is controlled with a serial periphery interface (SPITM). Key Features 1.4-2.7 GHz Frequency Range The TQM879008 features variable gain from 10 dB to 41.1 dB Maximum Gain at 2.5 GHz 41.1dB at 2.5 GHz, +47.5 dBm output IP3, and +27.3 dBm P1dB. The module operates from a single +5V supply and 31.5 dB Gain Range in 0.5 dB Steps is available in a compact 28-pin 6x6 mm leadless SMT +47.5 dBm Output IP3 package. +27.3 dBm Output P1dB Fully Internally Matched Module The TQM879008 is pin compatible with the TQM829007 Integrated Blocking Capacitors, Bias Inductors (0.7-1.0GHz, 0.25W DVGA) and TQM879006 (1.4-2.7GHz, 3-wire SPI Control Programming 0.25W 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.
