VARIABLE GAIN AMPLIFIERS - DIGITAL - SMT
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 accepts 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.

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.

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.

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.

Power-On Sequence
The ideal power-up sequence is: GND, Vdd, digital inputs, RF inputs. The relative order of the digital inputs are not important as long as they are powered after Vdd / GND
Note: Power-Up with LE= 1 provides normal parallel operation with D0 - D5, and PUP1 and PUP2 are not active.

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 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 Hittite upon request.
