Definitions

  • the invention relates to a radar transceiver, comprising at least one tunable with a control voltage oscillator, at least one mixer and at least one antenna for transmitting and receiving high-frequency signals, wherein the mixer mixes the received signal with the signal of the oscillator and outputs a demodulated signal.
  • Such radar transceivers i. Transceiver modules are used in the microwave and millimeter wave range for locating objects in the room or for determining the speed of, for example, vehicles.
  • a radar transceiver for locating objects in space and determining the speed emits highest-frequency signals in the form of electromagnetic waves, which are reflected by the target object, received by the radar transceiver again and further processed.
  • several such radar transceivers are interconnected to form an overall module.
  • Such radar transceivers are used in particular for the so-called distance warning radar, which is used for determining the distance of a further vehicle ahead of a vehicle and for issuing warnings when falling below a predetermined threshold value of the distance.

  • This object is achieved in a radar transceiver of the type described above according to the invention that the at least one oscillator, the at least one mixer and in addition the at least one antenna on a single chip in a plane are arranged side by side. Due to this structure, all radar functions are arranged on a single chip. By avoiding expensive RF transitions, this limits the production to a simple sticking of the chip (MMICs) on any low-frequency printed circuit board, wherein an electrical connection between circuit elements of the circuit board and the chip is required only in the low-frequency or DC range.

  • the mixer 120 is further supplied with the antenna signal of the patch antenna 140.
  • this received signal of the patch antenna 140 is mixed with the signal of the oscillator 110, and a demodulated signal is output after amplification in the intermediate frequency amplifier 130 is applied to corresponding bond pads 135 and from there via low-frequency known bonding wires to components on a circuit board 400, on which the chip is arranged (see Fig .. 3), is forwarded.
  • the oscillator 110 For the voltage supply of the oscillator 110 further bond pads 112 are provided, further provided for frquency tuning bond pads 115, which are all arranged in the plane of the chip 100.
  • the oscillator 110 is stabilized via an internal LC resonant circuit. Its frequency can be detuned in a known manner via a dedicated tuning input, which is electrically connected to the bond pads 115.
  • the radar transceiver shown in Fig. 2 differs from that shown in Fig. 1 in that in addition to the oscillator 110, the mixer 120, the amplifier 130 and the antenna 140 is also a phase locked loop circuit (PLL circuit) 150 in the level of the chip 100 is arranged, which is provided for controlling the oscillator in a known phase locked loop.

  • the polyrod 200 see FIG. 3
  • the 200 has the task of bundling and emitting the electromagnetic energy of the antenna patch 140. Through such a polyrod 200, in particular, a vofocusing on a dielectric lens 220 takes place. There is no physical contact of the Polyrods 200 to the chip 100 itself, but the Polyrod 200 can be on a Printed circuit board, on which the chip 100 is disposed, be attached. The center of the polyrod 200 is arranged exactly above the center of the patch antenna 140, as is apparent from Fig. 3.
  • the advantage of the above-described radar transceiver is the fact that all components of the transceiver are arranged on a single chip 100. This not only allows easy production, but also high integration. In addition, the function disruptive RF line connections are so largely unnecessary.
