General Description
The HMC627LP5(E) is a digitally controlled variable
gain amplifier which operates from DC to 1 GHz,
and can be programmed to provide anywhere from
11.5 dB attenuation, to 20 dB of gain, in 0.5 dB steps.
The HMC627LP5(E) delivers noise figure of 4.3 dB
in its maximum gain state, with output IP3 of up to
+36 dBm in any state. The dual mode gain control
interface accepts either three wire serial input or 6
bit parallel word. The HMC627LP5(E) also features a
user selectable power up state and a serial output for
cascading other Hittite serially controlled components.
The HMC627LP5(E) is housed in a RoHS compliant
5x5 mm QFN leadless package, and requires no
external matching components.

Serial Mode
The serial mode is enabled then P/S is set to high. Data is entered LSB first and after the 6th shift clock cycle the LE
(Latch Enable) is pulsed High and then Low. See timing diagram below for reference.

Parallel Mode (Direct Parallel Mode & Latched Parallel Mode)
Direct Parallel Mode - The attenuation state is changed by the Control Voltage Inputs directly. The LE (Latch Enable)
must be at a logic high to control the attenuator in this manner.
Latched Parallel Mode - The attenuation state is selected using the Control Voltage Inputs and set while the LE is in
the Low state. The attenuator will not change state while LE is Low. Once all Control Voltage Inputs are at the desired
states the LE is pulsed. See timing diagram below for reference.

Power-Up States
Parallel PUP Truth Table
Using the Parallel PUP truth table the attenuator can
be turned on at a specific attenuation state. By using
the PUP1 and PUP2 line four different attenuation
states can be selected. It can also be used in the
Direct Parallel Mode using the Control Voltage Inputs
to select attenuation values.

Description
The circuit board used in the final 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.
