This SLIM is constructed on a common printed wiring board, the PWB-PLO.  Click to get full information on the Basic Phase Locked Oscillator.

SLIM-PLO-2
    Frequency output = 940 MHz to 1075 MHz. PLL is LMX 2326 (obsolete) or ADF 4118. The loop filter is passive (no op amp). Dual RF outputs, +10 dBm at J2 and J3. Phase noise at 1024 MHz is -99 dBc, 5 KHz away from carrier.
    R12 and C27 are optional.  Installed, they present a 50 ohm load to the driver.  Omitted, the PLL is high impedance CMOS logic.

Note: LM2326 shown at U2 is obsolete. Use ADF4118.
Note: R23 is not shown on schematic. It is used only when ADF 4112 is substituted for U2. It is placed from U2 pin 1 to ground.

LAY-PLO-2, Layout of SLIM-PLO-2
slim/layslim_plo_2.gif
    This layout is used as a parts locator.  Not to be used for ordering the PWB.  Please note that the picture shows that the PWB is a Rev A.  Rev B can be substituted.
Note: R23 is not shown on layout. It is used only when ADF 4112 is substituted for U2. It is placed on the available circuit pads at U2 pin 1 to ground.

    Special note about the Minicircuits VCO, U4, ROS 1500.  Minicircuits specifications show conflicting data.  Vcc is actually  +10 volts and it's output power is well over +8 dBm at 1024 MHz.
