General Description
The HMC707LP5(E) is a digitally controlled variable
gain amplifier which operates from 700 MHz to 1200
MHz, and can be programmed to provide between
-2.5 dB attenuation and 29 dB of gain, in 0.5 dB steps.
The HMC707LP5(E) delivers noise figure of 0.8 dB
in its maximum gain state, with output IP3 of up to
+38 dBm. The dual mode gain control interface ac-
cepts either three wire serial input or 6-bit parallel
word. The HMC707LP5(E) also features a user
selectable power up state and a serial output for
cascading other Hittite serially controlled components.
For 1900 MHz applications please refer to the
HMC708LP5(E) data sheet.

ATTENUATION STATE (dB)
Serial Control Interface
The HMC707LP5(E) 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.
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, attenuation state will stay constant while LE is kept low.

120491 Evaluation PCB
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Arlon 25FR or Roger 4350
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.
