From RF Requirements to Integrated Hardware
AWG develops RF and microwave systems from application-level requirements through architecture, detailed RF design, subsystem integration and verification.
Our engineering approach considers the complete signal chain — including frequency planning, gain and noise budgets, filtering, spurious performance, linearity, isolation, switching, control, power distribution, thermal management and mechanical integration.

Two-Stage Receiver Cascaded NF & Gain Estimator
Evaluate how first-stage LNA performance dominates your RF front-end receiver chain using the Friis formula:
F_total = F1 + (F2 - 1) / G1
Stage 1 provides 18.0 dB of gain, which suppresses Stage 2's 20.0 dB noise factor. The overall receiver NF degrades by only +3.57 dB beyond the bare LNA front-end.
