From a3da15e222201f5316fe9a835668fe228ab9caa4 Mon Sep 17 00:00:00 2001 From: Mark Meserve Date: Tue, 8 Jan 2019 16:48:21 -0600 Subject: rh: adjust frequencies for lo filter bank - Moves the cutover frequency for the 900 MHz LO filter from 900 to 975 MHz. This fixes an image issue in TX when transmitting near 325 MHz or 900 MHz. --- host/lib/usrp/dboard/rhodium/rhodium_constants.hpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host') diff --git a/host/lib/usrp/dboard/rhodium/rhodium_constants.hpp b/host/lib/usrp/dboard/rhodium/rhodium_constants.hpp index 2548abdd5..2aafe4a63 100644 --- a/host/lib/usrp/dboard/rhodium/rhodium_constants.hpp +++ b/host/lib/usrp/dboard/rhodium/rhodium_constants.hpp @@ -22,7 +22,7 @@ static constexpr double RHODIUM_LO1_MIN_FREQ = 450e6; // Hz static constexpr double RHODIUM_LO1_MAX_FREQ = 6e9; // Hz static constexpr double RHODIUM_LO1_REF_FREQ = 122.88e6; // Hz -static constexpr double RHODIUM_LO_0_9_GHZ_LPF_THRESHOLD_FREQ = 0.9e9; // Hz +static constexpr double RHODIUM_LO_0_9_GHZ_LPF_THRESHOLD_FREQ = 0.975e9; // Hz static constexpr double RHODIUM_LO_2_25_GHZ_LPF_THRESHOLD_FREQ = 2.3e9; // Hz static constexpr double RHODIUM_LOWBAND_FREQ = 450e6; // Hz -- cgit v1.2.3
