General Description  
The HMC627ALP5E is a digitally controlled variable  
gain amplifier which operates from 50 MHz 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 HMC627ALP5E 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 HMC627ALP5E also features a  
user selectable power up state and a serial output for  
cascading other Hittite serially controlled components.  
The HMC627ALP5E is housed in a RoHS compliant  
5x5 mm QFN leadless package, and requires no  
external matching components.

v00.1212  
0.5 dB LSB GaAs MMIC 6-BIT DIGITAL  
VARIABLE GAIN AMPLIFIER, 50 MHz - 1 GHz  
Serial Control Interface  
The HMC627ALP5E 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. 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.  
When P/S is low, 3-wire SPI interface inputs (SERIN, CLK, LE) are disabled and serial input register is loaded  
asynchronously with parallel digital inputs (D0-D5). When Le is high, 6-bit parallel data is transferred to the attenuator.  
For all modes of operations, the DVGA state will stay constant while LE is kept low.

Parallel Mode (Direct Parallel Mode & Latched Parallel Mode)  
Note: The parallel mode is enabled when P/S is set to low.  
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 above for reference.

PUP Truth Table  
Power-Up States  
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. If the LE is set to logic HIGH  
at power-up, the logic state of D0-D5 determines the  
power-up state of the part per truth table. The DVGA  
latches in the desired power-up state approximately  
200 ms after power-up.

Description  
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 connected  
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 Hit-  
tite upon request.
