Functional Diagram
General Description
The HMC926LP5E is a digitally controlled variable
gain amplifier 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 figure 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 first. 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.

PUP Truth Table
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

have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to

Note: The HMC926LP5E requires interconnection traces with matching components from RFO1 pin to RFI1 pin, and from RFO2 pin to RFI2 pin.
The proper component network (L2, C2, C4, C5, L4, L5, C8, L6, L7, C11 and C12) for 900MHz applications is provided in this schematic. The
performance of the HMC926LP5E would be sensitive to the placement of these components and variations in the component values. For best
performance use the identical component placement with same length transmission lines as shown in the Evaluation PCB – 900MHz. Contact to
factory if assistance is required on component placement and selection.
