NOTES: 1. 50 coaxial balun, 2 inches long.
2. Pins 5, 10 and 15 are grounds and connnected to VEE which is the component's side ground plane.
These pins must be decoupled to VCC; decoupling capacitors should be placed as close as possible to the pins.
3. RFC1 is 180 nH Coilcraft surface mount inductor or 190 nH Coilcraft 146–05J08.
4. Recommended source is a Coilcraft ™slot seven 7.0 mm tuneable inducto,r part #7M3–682.
5. The crystal is a parallel resonant, fundamental mode calibrated with 32 pF load capacitance.

NOTES: 1. 50 coaxial balun, 2 inches long.
2. Pins 5, 10 and 15 are grounds and connnected to VEE which is the component's side ground plane. These
pins must be decoupled to VCC; decoupling capacitors should be placed as close as possible to the pins.
3. RFC1 is 180 nH Coilcraft surface mount inductor.
4. RFC2 and RFC3 are high impedance crystal frequency of 10 MHz; 8.2 µH molded inductor gives XL > 1000 ..
5. A single varactor like the MV2105 may be used whereby RFC2 is not needed.
6. The crystal is a parallel resonant, fundamental mode calibrated with 32 pF load capacitance.
