PLL-Oscillator (Preliminary Info)  (19.09.14 )

The assembly described here is NO MORE AVAILABLE. Here some data:

bulletFrequency range: according to customer order in the range from 100 to 1500 MHz,
bulletTuning range: approx.  +/- 5% around center frequency
bulletOutput: 50 Ohm, +7 dBm (5 mW)
bulletProgramming via RS232 interface (9600 Baud)
bulletFix frequencies ( memory) : 16 frequencies can be stored in EEPROM, selectable by 4 switchen
bulletModulation: dual modulation for perfect response from as low as 5 Hz up to 50 kHz FM (up to 76 kBaud FSK)
bulletFine tuning +/- 20 kHz or more by DC voltage (potentiometer). Effective in RX and TX mode.
bulletRIT-Input  (e.g. for doppler compensation), selectable for positive or negative df/du. Effective only in RX mode.
bulletAFC-Input  (same as RIT but separate), selectable for positive or negative df/du. Effective only in RX mode.
bulletRIT, FINE and AFC can be disabled / enabled by software mommand.
bulletPower supply: 12 Volt +/- 20% or 5 Volt +/- 2%, 50-100 mA
bulletTemperature stability: The output frequency is temperature-compensated from -10 to +70 C by temperature sensor and software digital control of reference quartz.
bulletDimensions: approx. 55 x 90 mm
bulletPTT: in 'TX'-mode, the oscillator frequency may be shiftes bi some kHz for not to interfere the receiver frequency.
bulletFrequency input: The operating frequency is directly input in Hz via RS232, ranging from 0 to 99 GHz. The built-in processor calculates the oscillator frequency considering programmed IF or converter shift and (if applicable) frequency multipliers.
bulletStep width of oscillator: approx. 10 to 50 Hz. Programmable in 1 Hz steps.
bulletBUS-capability: For complex systems, you may control many PLL or other FUNKBUS devices parallel. Each device on the bus has a programmable unique address.

What do we plan?

We are planning to develop a series of assemblies to built special transmitters and receivers.

The PLL and the BUS RS232-FUNKBUS-adapter are the first parts available.

In future, we shall add the following assemblies:

bulletPLL   Programmable precision oscillator (AVAILABLE SOON)
bulletFE7   RF front end for 435 MHz UHF, 71 MHz IF output to URX, 506 MHz LO input (from PLL)
bulletFE2   RF front end for 1250 MHz (23 cm L-Band) with frequency doubler for LO,
110 MHz IF output to URX, 570 MHz LO input (from PLL)
bulletFE1   RF front end for 2450 MHz (13 cm  S-Band) with frequency multiplyer (4x) for LO,
110 MHz IF output to URX, 585 MHz LO input (from PLL)
bulletURX   Programmable receiver with switchable filters (up to 300 kHz bandwidth)  for  45 to 150 MHz
bulletIFD     Receiver for 10.7 or 71.00 MHz IF, wide band FM for up to 76 kBaud data receivers. (AVAILABLE)
bulletPA7   RF power amplifier for transmitters, input: 5 mW, output: 25 W
bulletARO  Antenna controller for tracking satellites using a FUNKBUS system
bulletMUX  Multiplexer for RF / Antenna / AF or DC switching unsing a FUNKBUS system
bulletBUS  Converter to connect a computer RS232 to the FUNKBUS system (required 1x per system) (AVAILABLE)

User Commands (some extracts from the users manual)

The commands used with the PLL have the syntax:

*AACCxxxxx <CR>

bulletFirst character is an asterisk (h2A)
bulletsecond and third character is the device address,
which must match the address stored in PLL-EEPROM
bulletCC defines the command to be executed
bulletxxxx is the (optional) parameter field for the specific command

With the following examples, we assume the address of the PLL device to be 'P1'.

Setting the Frequency (immediately)

*P1VO=00435000000 <CR>

The operating frequency is immediately set to 435 MHz.
(Note: VO = 'VFO'-mode, the 'O' is the character 'Oscar', not figure zero)

Programming the 16 frequencies

*P1Z0=00435000000 <CR>

The channel Number 0 is programmed to 435 MHz.
(Note: Z0 = Channel Zero, the '0' is the figure zero, not the character 'Oscar')

*P1Z1=00435000000 <CR>

The channel Number 1 is programmed to 435 MHz.

*P1Zy=00435000000 <CR>

The channel Number y (0, 1, 2...9, A, B, C, D, E, F is programmed to 435 MHz.
