RF Receiver Signal Chain

Antenna → LNA → mixer → IF filter → ADC → DSP, with annotated gains and frequencies.

Prompt

An RF receiver signal chain drawn left-to-right with 7 blocks connected by labeled arrows.

Block sequence:
1. Antenna (icon) — RF input
2. Band-pass Filter — center frequency f_c, bandwidth B
3. Low-Noise Amplifier (LNA) — gain G1 = 20 dB, NF = 1.5 dB
4. Mixer — local oscillator at f_LO, output at IF = f_c - f_LO
5. IF Filter — band-pass at IF, bandwidth B
6. ADC — sampling rate f_s, resolution N bits
7. DSP — digital baseband processing producing demodulated symbols

Above each block, a small frequency-domain spectrum thumbnail showing the signal's spectral support at that point.

Below each block, a one-line annotation listing key parameters (gain, noise figure, sampling rate, etc.).

Style: clean RF schematic, monochrome with one accent color, white background, sans-serif labels. Suitable for IEEE Communications / Microwave figures.

Use in Generator

When to use

For RF / wireless / radar papers and IEEE Communications-style signal-chain figures.

Variations

Direct-conversion (zero-IF) variant

Combine the mixer + IF filter into a single I/Q demodulator block at zero IF, with two parallel I and Q paths going into a complex-baseband ADC pair.

Tips

Show spectra above blocks. RF audiences read by spectrum, not block names.
Annotate gain and noise figure per block. Without them the figure is decorative.
Use one accent color across all spectra so the visual rhythm is consistent.

FAQ

Can I add a noise budget?

Add a small table at the bottom listing each block's noise figure and gain, plus the cascaded noise figure (Friis formula).
