The HMC926LP5E is ideal for:
• Cellular Infrastructure
• WiBro, WiMAX and LTE/4G
• Microwave Radio & VSAT
• Test Equipment and Sensors
• IF & RF Applications
Gain Control Range (in 0.5 dB Steps):
@ 900 MHz, +6.5 to +38 dB
@ 1900 MHz, +1 to +32.5 dB
@ 2600 MHz, -4 to +27.5 dB
High Output IP3: +45 dBm
Noise Figure: 4.4 dB
Convenient Serial Control Interface
±0.25 dB Typical Step Error
32 Lead 5 x 5 mm SMT Package: 25 mm2
The HMC926LP5E is a digitally controlled variable
gain amplier which operates from 700 MHz to
2700 MHz, and can be programmed to provide
between +6.5 dB to +38 dB of gain, in 0.5 dB steps
at 900 MHz. Gain control range is from +1 dB to
+32.5 dB at 1900 MHz and from -4 dB to +27.5 dB at
2600 MHz. The HMC926LP5E delivers noise gure of
4.4 dB in its maximum gain state, with output IP3 of
up to +45 dBm. The HMC926LP5E features a serial
only gain control interface, a user selectable power up
state, and a serial output for cascading other Hittite
serially controlled components.

Serial Control Interface
The HMC926LP5E contains a 3-wire SPI compatible digital interface (SERIN, CLK, LE). It is activated when P/S
is kept high. The 6-bit serial word must be loaded MSB rst. The positive-edge sensitive CLK and LE requires
clean transitions. Standard logic families work well. If mechanical switches were used, sufficient debouncing should
be provided. When LE is high, 6-bit data in the serial input register is transferred to the attenuator. When LE is high
CLK is masked to prevent data transition during output loading.

If LE is set to logic LOW at power-up, the logic state
of PUP1 and PUP2 determines the power-up state of
the part per PUP truth table. The DVGA latches in the
desired power-up state approximately 200 ms after
power-up.
Power-On Sequence
The ideal power-up sequence is: GND, Vs, digital
inputs, RF inputs. The relative order of the digital
inputs are not important as long as they are powered
after Vs / GND

The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
