Function:

converts VFO frequency to output RF frequency; includes crystal-controlled conversion oscillator

Input/Output:

• POWER: 9-15 VDC, 5.5 x 2.5mm power jack
• VFO IN: Zin = 200 ohms, expect 250 mV p-p RCA Jack
• RF OUT: Zo = 200 ohms, RCA Jack
• KEY IN: Zin >= 10K, RCA Jack (0V = key-down)

Operator Controls:

• No operator controls anticipated

Key Specs or Limitations:

• Gain (VFO to Output Voltage Gain): 10 - 15 db (fixed)
• XTAL controlled conversion Oscillator must be trimmable +/-1 KHz min
• Use crystals specified for 18-20 pf load capacitance
• Keying applies to either the VFO or XTAL oscillator, disabling that oscillator during receive periods
• Key-down enables output
• Backwave < 2 mV p-p
• Minimum 1 tuned tank in output circuit
