-===RF OUTPUT===+===RF Output===
 The EV1HMC8362LP6G and EV1HMC8364LP6G boards have a single RF output port (RF1). RF1 is supplied by a buffer amplifier that is common to all four VCO cores. The EV1HMC8362LP6G and EV1HMC8364LP6G boards have a single RF output port (RF1). RF1 is supplied by a buffer amplifier that is common to all four VCO cores.
 RF1 (J3) is a single-ended RF output that operates up to 26.6 GHz. The actual frequency range and power level at any given time depends on which model is being evaluated and the VCO core that is enabled. Consult the [[adi>HMC8362]] and [[adi>HMC8364]] data sheets for additional information relative to the specific model being evaluated for more information. RF1 (J3) is a single-ended RF output that operates up to 26.6 GHz.

-===LOOP FILTER===+===Loop Filter===
 Although the EV1HMC8362LP6G and EV1HMC8364LP6G boards do not incorporate the entire loop filter, they do provide the means to filter noise that may appear on the tuning port when evaluating only the VCOs.  Although the EV1HMC8362LP6G and EV1HMC8364LP6G boards do not incorporate the entire loop filter, they do provide the means to filter noise that may appear on the tuning port when evaluating only the VCOs. 
 By default, a 100 pF capacitor (C12) is placed near Pin 27 (VTUNE) of the [[adi>HMC8362]] and [[adi>HMC8364]] to filter high frequency noise that may couple onto the tune port path when evaluating the various VCOs.  By default, a 100 pF capacitor (C12) is placed near Pin 27 (VTUNE) of the [[adi>HMC8362]] and [[adi>HMC8364]] to filter high frequency noise that may couple onto the tune port path when evaluating the various VCOs.

 SMA Connector J2 provides means to connect the PLL CP output to the tuning port (VTUNE) when the EV1HMC8362LP6G and EV1HMC8364LP6G are used with an optional PLL evaluation board. J2 can also be used to manually tune the VCO within its band when evaluating the open-loop VCO performance.   SMA Connector J2 provides means to connect the PLL CP output to the tuning port (VTUNE) when the EV1HMC8362LP6G and EV1HMC8364LP6G are used with an optional PLL evaluation board.

-===SOFTWARE===+===Software===
 Currently there is no software available for the EV1HMC8362LP6G and EV1HMC8364LP6G because they can be evaluated without the use of software. However, the EV1HMC8362LP6G and EV1HMC8364LP6G are configured in a manner that allows use of a Linduino, Arduino Uno, or similar microcontroller board, which may be beneficial for users needing to develop and test switching algorithms for their application.  Currently there is no software available for the EV1HMC8362LP6G and EV1HMC8364LP6G because they can be evaluated without the use of software.

 The frequency vs. tune voltage listed in the following steps are specific to the EV1HMC8362LP6G, but the same process is applicable to the EV1HMC8364LP6G. The frequency range and performance are different.  The frequency vs. tune voltage listed in the following steps are specific to the EV1HMC8362LP6G, but the same process is applicable to the EV1HMC8364LP6G.
