Buffer with remote cascode topology

A transmitter, comprising:

• a frequency synthesizer having a local oscillator (LO) that generates an LO-output signal comprising a high-frequency periodic signal;
• an up-conversion circuit for up-converting signals to be transmitted by an antenna;
• and
• a buffer circuit for buffering said LO-output signal between said frequency synthesizer and said up-conversion circuit, said buffer circuit including a main transistor, a cascode transistor and a distribution line for transferring signals over a distance;
• wherein said cascode transistor of said buffer circuit is located substantially adjacent to said up-conversion circuit and substantially remote from said frequency synthesizer, and wherein said distribution line connects a drain of said main transistor to a source of said cascode transistor.

A communications terminal, comprising:

• a frequency synthesizer having a local oscillator (LO) that generates an LO-output signal comprising a high-frequency periodic signal;
• a down-conversion circuit for down-converting signals received by an antenna;
• and
• a buffer circuit for buffering said LO-output signal between said frequency synthesizer and said down-conversion circuit, said buffer circuit including a main transistor, a cascode transistor and a distribution line for transferring signals over a distance;
• wherein said cascode transistor of said buffer circuit is located substantially adjacent to said down-conversion circuit and substantially remote from said frequency synthesizer, and wherein said distribution line connects a drain of said main transistor to a source of said cascode transistor.
